    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: The application relates to sliding-window maximum a posteriori MAP decoding. In a MAP decoder, a method for determining binary states of received signals comprises receiving data bits, each bit being accompanied by at least one parity bit, providing each received data bit and parity bit with an address (16a) of a calculated extrinsic value (14a) and associated intrinsic data and storing the data bits, the parity bits and the extrinsic value address in a first memory (12).
