Title: Forward Error Correction decoder suitable for use with data comprising variable padding
Inventor: VESMA JUSSI
IPC: H04N19/89
Filed: 2003-11-05
Abstract: Elements of a coding table which are error-free are found at S2. At S3 corresponding elements in an erasure information table are completed, indicating that the elements in the coding array are correct. A counter is initialised at Nmax, which is the maximum number of errors that can be corrected, at S4. At S5, the row of the erasure information table is scanned beginning from the first parity column for empty elements. Each empty parity date element of the erasure information table row is marked as incorrect at S7 then, at S9, the elements of the erasure information table are scanned from the first column of the application data and zero padding section for empty elements. Each time an empty element is marked as incorrect the counter is decremented (step S8, S12). When the counter becomes equal to zero, operation proceeds to step S14 where the decoder operates to fill remaining empty elements in the erasure information row as correct even though they may be incorrect.

Title: WLAN access scheduling for multimedia data transfer comprising isochronous streams and asynchronous bursts
Inventor: HO JIN-MENG
IPC: H04L12/56
Filed: 2004-03-31
Abstract: The present invention provides a system for scheduling access times for transmitting data traffic in a WLAN (10). The data traffic includes both isochronous streams and asynchronous bursts characterized by widely varying parameter values. A succession of service periods TSP is generated, each having adjustable length and including two or other number of primary access intervals. TPP1, TPP2. The service periods may also be adapted to include one or more asynchronous burst periods or epochs, TAE1, TAE2 each immediately following a primary access interval. A hybrid coordinator (30 fig 1) located at the AP (12, fig 1) of the WLAN operates to schedule access times for each ischronous stream only during a primary access interval, or an immediately following extension period, TPE1, TPE2. Asynchronous bursts are scheduled for access times only during asynchronous burst periods. Thus, an access time scheduling is made available that can readily adapt WLAN access to continually changing data traffic conditions, and thereby provide QoS by scheduling access times accordingly.

Title: Source synchronous interface using variable digital and analog delay lines
Inventor: GAUTHIER CLAUDE R
IPC: H04L7/00
Filed: 2003-08-06
Abstract: A source synchronous interface determines an amount of delay for an incoming data signal and a phase offset for a latch device that latches the incoming data signal. A delay locked loop may be a dual loop delay locked loop, in which case, the loops may use a low jitter, local clock signal and an input clock signal that was transmitted with the data signal. The low jitter, local clock signal may provide a stable source from which to derive good clock signal edge transitions. The input clock signal may be used to determine the long term clock signal drift. A finite state machine within the dual loop delay locked loop may provide the necessary information for the amount of delay and the phase offset. The delay of the incoming data signal is produced by an analog or digital delay line.

Title: Mitigating interference between wireless systems
Inventor: KITCHIN DUNCAN
IPC: H04L12/56
Filed: 2001-08-29
Abstract: Two separate radio frequency networks (e.g. WLAN and Bluetooth) may be operated within interference distance from one another in a way which mitigates the possibility of interference. A device node receives a modulated noise signal and identifies a characteristic in the noise signal without demodulating the signal. The identified characteristic is used to identify the noise signal, (e.g. as a Bluetooth signal) and predict the behaviour of the signal without demodulating the signal. Being able to identify and predict the behaviour of the noise signal without demodulating the signal is useful as it removes the need for a complaint receiver, e.g. demodulation of a Bluetooth signal would require a Bluetooth complaint receiver. The received signal strength indicator (RSSI) signal may be used and the timing and characteristics of the interfering signal may be determined, e.g. a Bluetooth signal includes a telltale repeat interval or pattern and information about the synchronization reference point and slot occupancy probability can be used to develop a statistics package that indicates a probability of transmission from the interferer at any given time. Each node in a network can transmit information about its local noise source to each of the other nodes in the network so that a first node wishing to transmit to a second node can use the information on the noise at the second node to determine the best transmission time.
