Recent studies have determined the performanceofTCH(n,k) (Tomlinson, Cercas, Hughes)codesin different environments, namely for mobile satellite channels for whichTCHcodesofsmall length n (e.g. 16) present some advantages when compared withTCHcodesofhigher length (e.g. 256). However, the correlation characteristicsofTCHcodesofsmall length present some peaks that deteriorate its performance. In this paper we present a method to properlybit-map the incoming data bits to thecodewords so as to minimize this effect. The improvement in performance was obtained by simulation and is compared with previous known results.
