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: Un método de control automático de ganancia (AGC) de acuerdo con la presente aplica una ganancia inicial a través de un circuito AGC digital en una ranura de tiempo que es determinada utilizando una ganancia calculada final de la misma ranura de tiempo en la trama previa junto con un factor de desplazamiento. Se activa una función de borrado para un bloque de muestra de datos cuando el número de muestras de datos saturadas que son detectadas dentro del bloque, excede un valor umbral. La medición de potencia hecha por el circuito AGC y utilizada para actualizar la ganancia es ajustable en base al número de muestras de datos medidas que están saturadas. Esto elementos proveen una función de limitación de ganancia y permiten limitar el rango dinámico para un procedimiento de senal adicional.

Abstract: A method for wireless communication is disclosed. Data symbols of a received communication are estimated and own-UE and other codes are detected using the estimated data symbols to generate a candidate code list. The own-UE codes and other-UE codes are then from the candidate code list to include in a detected output list based on thresholds for own-UE codes and other-UE codes.

Abstract: A method and system for performing initial cell search in wireless communication system wherein unsuitable cells are excluded is disclosed. Stored frequencies are searched exhaustively and initial frequencies are search non-exhaustively. Initial frequencies may be searched exhaustively in certain circumstances. When performing exhaustive initial cell searches, primary synchronization codes that lead to unsuitable cells are excluded fro m subsequent initial cell searches performed on the same frequency.
