A communication system economically mitigates the frequency-selective multipath effects and co-channel interference in wireless LANS. The communication system comprising a wireless local area network (LAN) formed by a plurality of spacially separated transceivers (TR, TR'). Each of the transceivers has a transmitting section ( 10 ) for transmitting data by a combination of dual code spread spectrum techniques and a receiving section ( 12 ) for recovering the data. The receiving section ( 12 ) comprises a plurality of diversity antennas (ANT 1 to ANT n), an adaptive forward equal gain combiner ( 60 ) having a plurality of branches ( 62 to 74 and 62 ' to 74 '), each branch being coupled to a respective one of the diversity antennas. The adaptive forward equal gain combiner ( 60 ) selects a signal in one of the branches as a reference signal and co-phases the signals in the remaining branches with the reference signal. |
