Abstract(in English) | Near-far problem is one of the big problems in spread spectrum communications.Conventionally as the countermeasures against near- far problem such methods as transmission power control and crosscorrelation cancellation have been proposed.However,the former can not be used in a network without base station and the later is used only under the condition that a receiver already knows the spread sequences of interfering signals.Therefore,we would like to propose the interference cancellation system whatever the receiver doesn′t know the interfering spread sequence s.It can be realized by the estimation of the unknown spread sequence of the interference,making a replica of the interfering signal,and the subtraction of the replica from the received signal. |
