ABSTRACT:
A remote unit transmits data by Frequency hopping over a set of frequencies to a base station. A plurality of antennas at the base station receives the transmitted frequency hopped data. An optimal combining of each antenna's received hopped data for a particular frequency is determined. Data is selectively transmitted using the plurality of antennas from the base station to the remote unit over the particular frequency. The selectively transmitting is selected using the optimal combining.
