Abstract
A wireless communication system including a receiver adapted to receive data at 10 Mbps or greater is described. The received signals are preferably binary (BFSK) and/or quaternary (QFSK) shift keying signals limited to a bandwidth of less than or equal to 5 MHz. The receiver includes a demodulator capable of operating in a multipath environment. In one embodiment, a frequency-hopping wireless communication system is used and the bandwidth limitations concern the bandwidth at each hop.
