    Abstract: Components and method are provided to efficiently process wireless communications data where prior knowledge of the 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), a format detector and a de-interleaver. 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 received in each time frame. The de-interleaver is preferably configured to de-interleave the stored data despread by the RCRP for each respective time frame into the number of physical channels determined by the format detector for the respective time frame.

    Abstract: A wireless communication method and system for assigning multi-paths to Rake receiver fingers. A Rake finger assignment database is established in which multi-path signals (300) are categorized into a verified group and an unverified group. Each multi-path is assigned to an individual bin in the database. Each bin includes a pilot phase data field (310), an antenna data field (315), a code data field (320), an averaged signal strength data field (325), an assigned flag data field (330), a verification flag data field (335), an update flag data field (340), an assigned Rake finger number data field (345) and an assignment time counter data field (350). The multi-path signals in the verified group are further categorized into an assigned subgroup and an unassigned subgroup. During a measurement interval, each of a plurality of newly measured multi-path signals is compared to the multi-path signals in the database and is processed accordingly.

    Abstract: A plurality of communication signals have differing spreading codes. Each communication has an associated code comprising chips. For each chip of each communication, a vector of that chip convolved with an impulse response is produced. For each communication, support blocks comprising the chip vectors are produced. A number of the chip vectors in a support block is based on that communication's spreading factor. A system response matrix is assembled. The system response matrix has symbol sub-matrices. Each symbol sub-matrix comprises a support block from each communication. Data of the communications is detected using the symbol response matrix.
