Title: Pilot transmission schemes for wireless multi-carrier communication systems
Inventor: SMEE JOHN E
IPC: H04W24/08
Filed: 2004-01-07
Abstract: Pilot transmission schemes suitable for use in wireless multi-carrier (e.g., OFDM) communication systems. These pilot transmission schemes may utilize frequency, time, or both frequency and time orthogonality to achieve orthogonality among the pilots transmitted by multiple base stations on the downlink. Frequency orthogonality is achieved by transmitting pilots on disjoint sets of subbands. Time orthogonality is achieved by transmitting pilots using different orthogonal codes (e.g., Walsh codes). The pilots may also be scrambled with different scrambling codes, which are used to randomize pilot interference and to enable identification of the transmitters of these pilots. Pilot interference cancellation may be performed to improve performance since subbands used for data transmission by one transmitter may also be used for pilot transmission by another transmitter. Pilot interference is estimated and then subtracted from received symbols to obtain pilot-canceled symbols having improved quality.

Title: Efficient modulation of rf signals
Inventor: FILIMONOV NIKOLAI
IPC: H04L27/36
Filed: 2004-01-07
Abstract: Coherent modulator architectures of wireless communication devices are used for the processing of modulated RF signals. The circuitry comprises a DC/DC converter (204) which serves as an amplitude modulator, different amplification stages (204, 206, 212, 214), a bypass path (215) to selectively bypass at least one (214) of a cascade of class C, D, E, or F power amplifiers (212, 214), and an automatic power control (APC) loop (220) that guarantees power stability over time and temperature variations. To increase the efficiency of the amplification procedures needed for an amplitude modulation, the slow (narrowband) high-level components (222) and the fast (wideband) low- level components (224) of the signal representing the magnitude (I x Lp (t) l) of an I/Q modulation state (xLp (t)) are amplified in separate stages (204, 206) and are then combined by sup plying the low-level components (224) to a power amplifier (206) whose gain is controlled depending on the amplified high-level components (222). At least one (214) of said cas cade of power amplifiers (212, 214) can selectively be bypassed by a bypass circuitry (215), which is used for the sake of efficiency optimization. In the bypass mode, the DC power supply (Vbat) of the bypassed power amplifier (214) can selectively be switched off by means of a switch (SZ). It is used when the needed RF signal power is low and the driver PA (212) is able to produce enough gain.

Title: Optical disk recording/reproducing apparatus
Inventor: ANDOH HITOSHI
IPC: G11B7/095
Filed: 2004-03-17
Abstract: An optical disk recording/reproducing apparatus capable of making the record quality the best. Data is recorded while shifting the tracking by gradually adding an offset voltage (bias value) to a tracking error signal. Thereafter, the data in the recorded area is reproduced, and the jitter value (indicating the read state of address information) of biphase data generated from a reproduction RF signal is detected by means of a biphase jitter detection circuit (20). As a shift value of the tracking bringing the data read state the best, a CPU (14) determines an offset voltage value at which the jitter value of the biphase data is the smallest, according to the offset voltage value (the shift value of tracking) added to the tracking error signal and the detected jitter value of the biphase data, and records it in a memory (15).

Title: Radio controlled clock, electronic device, method for controlling radio controlled clock, and program for controlling reception of radio controlled clock
Inventor: NAKAMURA HIDENORI
IPC: G04R20/08
Filed: 2004-09-30
Abstract: There is movement status detecting means (5) that includes an electric power generation detecting circuit (51) for detecting the voltage of an electric power from electric power generating means (4) and that also includes a determining part (52) for determining, from the voltage of the generated electric power from the electric power generation detecting circuit (51), whether a radio controlled clock (1) is moving. When the movement status detecting means (5) outputs a non- movement detecting signal indicative of no movement of the radio controlled clock (1), a reception part (2) is activated to receive a standard radio wave so as to correct the time displayed on time displaying means (3). Since the standard radio wave is received during no movement of the radio controlled clock (1), precise time information can be acquired and further the probability of successful reception can be improved, whereby the reliability of reception of the standard radio wave can be improved.
