Abstract

It is well known that channel state information (CSI) can be used by the receiver to improve the BER performance of coded spread spectrum communications. Unfortunately, this information is generally not available, and has to be estimated by the receiver. The paper presents an efficient method for estimating jammer parameters, based on an iterative clustering technique. The approach presented is applicable to slow frequency hopping PSK (SFH-PSK) systems corrupted by partial band (PB) jamming. Simulations of the proposed method show that BER performance is, in most cases, very close to perfect CSI.<>
