摘要： An adaptive equalizer including an equalizer filter and a tap coefficients generator used to process a sample data stream derived from a plurality of received signals is disclosed. The tap coefficients generator includes an equalizer tap update unit, a vector norm square estimator, an active taps mask generator, a switch and a pilot amplitude reference unit used to minimize the dynamic range of the equalizer filter. A dynamic mask vector is used to mask active taps generated by the equalizer tap update unit when an unmasked signal output by the equalizer filter is selected by the switch to generate an error signal fed to the equalizer tap update unit. A fixed mask vector is used to mask active taps generated by the equalizer tap update unit when a masked signal output by the equalizer filter is used to generate the error signal.

摘要： A normalized least means square (NLMS) equalizer including two equalizer filters is disclosed. In one embodiment, a single correction term generator is used to generate correction terms for tap coefficient updates of each of the equalizer filters based on a pilot signal.

摘要： A wireless communication method and apparatus for detecting and decoding enhanced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test. The WTRU then generates an acknowledgement (ACK) message or a non-acknowledgement (NACK) message based on the detected H-ARQ indicator. A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

摘要： A method and apparatus for automatically correcting the frequency of a local oscillator of a receiver. A primary common pilot channel (CPICH) code sequence is generated by a CPICH code generator based on a reference cell identification signal and a frame start signal. The received despread CPICH code sequence is used to generate an estimated frequency error signal. A control voltage signal is generated by a control voltage generator based on the estimated frequency error signal. The CPICH code generator generates the CPICH code sequence based on signals received from a high speed downlink packet access (HSDPA) serving cell when HSDPA is active, or a timing reference cell when HSDPA is not active. The present invention achieves full maximum ratio combining gain when space time transmit diversity (STTD) is used, even without receiving a transmit diversity indication.
