    Abstract: The present invention has many aspects. One aspect of the invention is to perform equalization using a sliding window approach. A second aspect reuses information derived for each window for use by a subsequent window. A third aspect utilizes a discrete Fourier transform based approach for the equalization. A fourth aspect relates to handling oversampling of the received signals and channel responses. A fifth aspect relates to handling multiple reception antennas. A sixth embodiment relates to handling both oversampling and multiple reception antennas.

    Abstract: A plurality of communication signals is received. Each communication signal has an associated code. At least two of the communication signals has a different spreading factor. The associated codes have a scrambling code period. A total system response matrix has blocks. Each block has one dimension of a length M and another dimension of a length based on in part M and the spreading factor of each communication. M is based on the scrambling code period. Data of the received plurality of communication signals is received using the constructed system response matrix.

    Abstract: Components and method are provided to efficiently process wireless communications data where prior knowledge of a specific format of the communication data is not available. A wireless transmit receive unit (WTRU) is configured for use in a wireless communication system where communication data for selected channels is transmitted in system time frames in formats selected from among a set of predefined formats. The WTRU has a receiver, a memory, a received chip rate processor (RCRP) and a format detector. The RCRP is preferably configured to despread each wireless signal of spread data received in each time frame using a minimum spreading code or other appropriate key sequence and to store resultant despread data for each respective time frame in the memory. The format detector is preferably configured to determine the number of physical channels and the respective spreading factor for each physical channel for the wireless signal of spread data.

    Abstract: A receiving device comprising circuitry configured to receive a signal including pilot bits transmitted by a plurality of antennas; wherein the received signal includes data for a single user that was combined with different sequences producing a plurality of combined data sequences; wherein antenna-specific weights for the plurality of antennas are applied to each of the combined data sequences and the antenna specific weights are applied to pilot bits added with the combined data sequences; wherein the received signal includes the pilot bits for each of the plurality of antennas; and wherein the pilot bits for each antenna have a different sequence for that antenna; the circuitry is further configured to derive preferred weights for the received signal based on the pilot bits for each antenna; the circuitry is further configured to recover data for the single user from each of the combined data sequences; and the circuitry is further configured to combine data from the recovered data for the single user from each of the different sequences.

    Abstract: A receiver comprises a plurality of antenna elements for receiving a data signal. Each antenna element has a plurality of Rake fingers. Each Rake finger processes a received multipath component of the received data signal of its antenna element by applying a complex weight gain to that received multipath component. A complex weight gain generator determines the complex weight gain for each Rake finger for each antenna element using an input from all the Rake fingers. A summer combines an output of each Rake finger to produce an estimate of the data signal.
