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 zero forcing. 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 zero forcing factor that is determined as [(H*·H)−1·H*]. More specifically, the H* represents channel matching and (H*·H)−1 represents interference cancellation due to channel fading over time or frequency.
