    摘要: A method and apparatus for detecting transmission of a packet in a wireless communication system are disclosed. A packet includes a preamble which comprises multiple repetition of a training sequence. A signal is detected and the detected signal is correlated with a delayed version of the detected signal which is delayed by a predetermined delay time to generate a sequence of correlations. The correlations are normalized. A difference between a first normalized correlation and a second normalized correlation that are separated by the predetermined delay time is calculated. The difference is compared to a threshold. A transmission of the packet is detected based on the comparison. The first and second normalized correlations may be averaged over first and second averaging periods, respectively. A point generating a maximum difference may be identified, and packet synchronization may be performed based on the identified point.

    摘要: A method and apparatus for encoding and decoding high speed shared control channel (HS-SCCH) data are disclosed. For part 1 data encoding, a mask may be generated using a wireless transmit/receive unit (WTRU) identity (ID) and a generator matrix with a maximum minimum Hamming distance. For part 2 data encoding, cyclic redundancy check (CRC) bits are generated based on part 1 data and part 2 data. The number of CRC bits is less than the WTRU ID. The CRC bits and/or the part 2 data are masked with a mask. The mask may be a WTRU ID or a punctured WTRU ID of length equal to the CRC bits. The mask may be generated using the WTRU ID and a generator matrix with a maximum minimum Hamming distance. The masking may be performed after encoding or rate matching.

    摘要: The invention is directed to a system for dynamically correcting an electromagnetic wave by processing two or more aspects of the electromagnetic wave along two or more separate signal paths; comparing an expected value for at least one of the aspects of the electromagnetic wave with an actual value for the aspect of the electromagnetic wave to generate a correction signal; and applying the correction signal to at least one other aspect of the electromagnetic wave. The aspects of the electromagnetic wave to be processed may be amplitude and phase, where the comparison may be along the phase path and the adjustment along an analog portion of the amplitude path. A digital phase locked loop may be used for the comparison and to generate the correction signal; and a bank of pipeline registers may be used to adjust the amplitude path.
