SIMPLE SMART-ANTENNA SYSTEM FOR MUD-ENABLED CELLULAR NETWORKS

摘要

PURPOSE: A simple smart-antenna system for MUD(Multi-User Detection)-enabled cellular networks is provided to increase the capacity of total system by reducing or removing interference signals and maximizing desired signals. CONSTITUTION: A transmitter of a base station using MUD includes antennas of j number, a plurality of weight value generators, one or more linear processors, and a vector adder. The antennas(30) are used for transmitting parallel data input signals. The weight value generators are used for generating indexed complex weight values according to each data signal and each antenna number. The linear processors are used for processing the weight values by maximizing a power gain of a desired point and de-emphasizing a power gain of an undesired point. The vector adder is used for forming channel impulse response data for the transmission of the antennas.
