Wireless system having channel fading compensation using minimum mean square error

摘要

A MISO wireless LAN includes multiple inputs and a single output. The present invention includes a method and apparatus of compensating for time sensitive or frequency sensitive channel fading using minimum mean square error. The time sensitive channel fading is represented by the vector [H(t)], and the interference compensation is performed by multiplying the incoming data by a minimum mean square error factor that is determined as [(H*·H+1/SNR)⁻¹·H*]. More specifically, the H* represents channel matching and (H*·H+1/SNR)⁻¹ represents interference cancellation due to channel fading over time or frequency.
