ABSTRACT:
A radio communication system and method for minimizing co-channel interference comprises a technique for communicating between first stations and second stations. The technique involves: i) processing, at a first station, first signals into a form representative of modulated radio signals; ii) combining the representations to form a number of transmit signals using a set of combining parameters; iii) transmitting the transmit signals using a transmitter and antenna for each of the signals; iv) receiving the transmit signals at the second stations to produce received signals; v) measuring at the second stations an amount received of at least one unwanted signal relative to the amount of wanted signal received to produce measurement results; vi) transmitting the measurement results from the second stations to the first station; and vii) receiving the measurement results at the first station and using the results to modify the combining parameters such that unwanted signals received at the second stations are reduced and wanted signals enhanced. The measuring step includes the step of correlating received signals with known signals to produce the amount of at least one unwanted signal, and the amount of wanted signal.
