Patent TW-515148-B (TW)
Title: Method and apparatus for demodulating signals processed in a transmit diversity mode
Inventor: ROWITCH DOUGLAS NEAL
IPC: H04B1/7075
Filed: 2001-06-14
Granted: 2002-12-21
Abstract: Demodulator architectures for processing a received signal in a wireless communications system. The demodulator includes a number of correlators coupled to a combiner. Each correlator typically receives and despreads input samples (which are generated from the received signal) with a respective despreading sequence to provide despread samples. Each correlator then decovers the despread samples to provide decovered ""half-symbols"" and further demodulates the decovered half-symbols with pilot estimates to generate correlated symbols. The decovering is performed with a Walsh symbol having a length (T) that is half the length (2T) of a Walsh symbol used to cover the data symbols in the transmitted signal. The combiner selectively combines correlated symbols from the assigned correlators to provide demodualted symbols. One or more correlators can be assigned to process one or more instances of each transmitted signal. The pilot estimates used within each assigned correlator to demodulate the decovered half-symbols are generated based on the signal instance being processed by that correlator.

Granted: 2002-12-21
Abstract: The invention relates to a method for downloading big-size information using WAP that sets up a special web page program block (such as ASP) in a wireless electronic device (such as PDA) and server of a wireless network, allowing to issue a request for downloading big-size information to the server while the electronic device is utilizing the block format, the server reads the corresponding document from a database in accordance with the request contents, then divides the document into multiple information blocks in accordance with the data transmission limitation of the wireless network and responds to the electronic device with the block format for all of the information blocks, making the electronic device issue command to download each information block data one-by-one to the server and the server sequentially forward each information block of the document to the electronic device in accordance with such command. As such, the electronic device can combine those received information blocks as a complete document to achieve the limitation of WAP in downloading big-size information.

Title: Method and apparatus for data transmission over an AC-97 protocol link
Inventor: MALECK TIMOTHY C
IPC: G06F3/16
Filed: 2001-09-21
Granted: 2004-05-11
Abstract: An audio encoder/decoder (AC)-97 protocol link is used for concurrent data communication between AC-97 protocol devices and non-AC-97 protocol devices. The Tag data in an AC-97 data frame is used to select specific CODECs and to determine which data time slots to ignore or accept. Since telephone voice and data communication uses only the Tag data and one other of the data frame time slots, eleven slots are available for communication using non-AC-97 protocol devices concurrent with telephony communications. Ethernet, home phoneline network alliance (HPNA), attachment unit interface (AUI) are some of the data communication protocols that may be employed using embodiments of the present invention. An AC-97 data communication controller may modified with additional logic and control lines to support additional features of non-AC-97 protocol devices.

Title: Turbo code decoder for communication system
Inventor: DING YUN-REN
IPC: H03M13/00
Filed: 2001-12-11
Granted: 2003-04-21
Abstract: A turbo code decoder using the design of VLSI architecture of both parallel and systolic array is disclosed, in which the decoder is designed by systolic array VLSI. Since the output of previous stage can be the input of the next stage, the advantages of parallel and pipelined computation can be achieved sufficiently. The time delay takes only N+M-2 time units, which is shortened for about 1/5 compared to the 5*(N+M) time units provided by the sequential computing structure of the prior art. The decoding yield rate is higher than that of the traditional decoder for about 5*(N+M) times. Although the gate counts of the circuit is about 5*(N+M) times that of the traditional decoder, the complexity of hardware is pretty easy to be resolved nowadays as the VLSI technology advances rapidly. It is an invariant trend to invest in the hardware cost to obtain the increase of speed.

Granted: 2004-01-11
Abstract: There is provided a semiconductor integrated circuit device wherein functional circuit groups are arranged on a chip in a direction spreads, which aims to enhance layout efficiency and to prevent deterioration of element characteristics. A unit wiring region IL1P is constituted outside of a power voltage wiring VCC, a part of a second region BIP and a unit wiring region IL1N is constituted outside of a reference voltage wiring VSS, a part of a second region BIN. Within the second wiring regions BIP and BIN, connection wirings 11, 12A, 13, 14 are wired. These connection wirings connect between units within the logic circuits CIA11, CIR12 or between the logic circuits CIR11, CIR12. There is only arranged an input/output wiring region IOL1 on a first region A1 located between the power voltage wiring VCC1 and the reference voltage wiring VSS1. Since no unit wiring region exists in the first region A1, width of the first region A1 can be laid-out short. Accordingly, connection wiring between PMOS/NMOS transistors can be shortened, areas of an N-type well region NW1 and a P-type well region PW1 can be made small. Layout efficiency and circuit characteristic can be enhanced, as a result.

Title: Image reject circuit using sigma-delta conversion
Inventor: SMITH GARY
IPC: H04N1/40
Filed: 2002-12-13
Granted: 2006-06-01
Abstract: In a digital IF (intermediate frequency) downconversion circuit, in-phase and quadrature signal components are processed in the form of a single serial digital bit stream through a set of simple logic in combination with a reconstruction filter. A source digital oscillator supplying digital signal mixers employs an oversampled digital word of four bits in length, all of which are binary weighted, to achieve at least sixteen levels of accuracy for a sine wave mixing signal without significant phase or amplitude error. The mixer mixes the digitized serial bit stream according to the clock with output of a four-bit wide table representing the source oscillator and the in-phase and quadrature signals are recombined digitally, followed by binary weighting using weighted resistors coupled into a filter. Thus, image rejection is a digital function which is unaffected by resistor tolerance.
