Abstract: Multi-user detection (MUD) performance is optimized to eliminate redundant use of power during processing. An overbuilt A-matrix, i.e., a system response matrix, is provided. The overbuilt A-matrix uses all possible codes, e.g., all codes identified in a candidate code list (CCL) provided by blind code detection (BCD). The overbuilt A-matrix is passed to the MUD which extracts only those rows or columns required for codes that have actually been received, thus eliminating the need to recompute whitening matched filter (WMF) outputs that do not correspond to the actually received code.
Abstract translation: 优化多用户检测（MUD）性能，以消除处理过程中冗余电源的使用。 提供了一种过度建立的A矩阵，即系统响应矩阵。 过量的A矩阵使用所有可能的代码，例如由盲代码检测（BCD）提供的候选代码表（CCL）中标识的所有代码。 过量的A矩阵被传递给仅提取实际已经接收的代码所需的行或列的MUD，从而不需要重新计算与实际接收的代码不对应的白化匹配滤波器（WMF）输出。

Abstract: Processing elements (54-54N) are utilized for solving linear systems. One embodiment (Fig. 3B) projects matrix elements along a diagonal of the matrix onto scalar processing elements to determine a Cholesky factor. Another embodiment uses a two-dimensional scalar array to determine a Cholesky factor. For matrices having a limited bandwidth, the processors (54-54N) may be used to reduce the number of processors used.

Abstract: 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.

Abstract: A method and system for performing many different types if algorithms utiliz es a single mathematical engine (30) such that the mathematical engine is capab le of utilizing the same multipliers for all of the algorithms. The mathematica l engine includes a selectively controlled parallel output register (33), at least one selectively controlled memory (31), and a plurality of processing elements (40). The output register, the memory and the processing elements a re selectively controlled depending upon the algorithm to be performed.
