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: Method and apparatus for performing midamble cancellation to remove midamble interference from the convolution tail of data field 1 and the first W−1 chips of the midamble field which results from the delay spread of the multipath channel and for canceling the first W−1 chip midamble spread in the data field 2, which operations are performed substantially simultaneously. The received burst, typically a TDD burst, is stored, the midamble interference and the corresponding parts in the received burst is removed and the resulting burst is applied to a multi-user detector to obtain the symbol sequences.
