A subscriber unit receives a plurality of first spread spectrum signals. Each first spread spectrum signal has a first code. An impulse response of multipath components of each received first spread spectrum signal are analyzed to determine a first received component of that received first spread spectrum signal. In one embodiment, for each received first spread spectrum signal, a second spread spectrum signal having a second chip code time synchronized to the first received component of that received first spread spectrum signal is transmitted. In another embodiment, a code timing difference is determined between the first received components of the received first spread spectrum signals. The code timing difference is transmitted.
