USER EQUIPMENT USING ARRAY PROCESSING FOR DATA DETECTION

A wireless transmit receive unit (WTRU) recovers data from a plurality of data signals received as a received vector. The WTRU determines data of the received vector by determining a Cholesky factor of an N by N matrix and using the determined Cholesky factor in forward and backward substitution to determine data of the received data signals. The WTRU comprises an array of at most N scalar processing elements. The array has input for receiving elements from the N by N matrix and the received vector. Each scalar processing element is used in determining the Cholesky factor and performs forward and backward substitution. The array outputs data of the received vector.
