Method for auxiliary pilot cancellation in wireless network reverse link

Abstract

In carrying out a method for auxiliary pilot cancellation in a wireless network reverse link, a base station receives signals from various wireless units over the reverse link. Some of the wireless units may transmit auxiliary pilot signals when transmitting high-speed packet data. For each active wireless unit, the base station monitors the received signals for the presence of auxiliary pilot signals. When present, the auxiliary pilot signals are regenerated, combined, and removed from the composite received signals, forming an interference-free output signal. The output signal is routed to an array of decoding units (one for each active user), for decoding data traffic. The auxiliary pilot signals may be routed to the decoding units for use in channel estimation calculations.
