The choice of an air interface technique to enable broadband wireless communications has been the subject of extensive research. This article describes an air interface for 2 Mb/s wireless mobile packet data services. The key enabling technique is a reduced-complexity broadband equalizer which provides a delay spread tolerance of up to 50 μs. The proposed air interface emphasizes high packet throughput, robust performance, low packet overhead, and low-cost low-power VLSI implementation
