Title
An upper bound of binary phase precoding with turbo codes in frequency selective fading channels.
Abstract
The concatenated system of binary phase precoding and turbo codes is proposed in this paper. Its performance is presented by using an analysis method. The upper bound of constituent encoders (5,7) and (23,35) with constraint lengths of 3 and 5 respectively, are computed by varying both of the small information block size and spiral curve constants (coding rate ½). Result shows that a significant performance is achieved with a higher gain than the result of the same constituent convolution code using with the same precoding scheme. In addition, this concatenated system is also compared to other similar system where trellis coded modulation with precoding is used. The better result confirms that this pro- posed system is a new powerful ISI cancellation method that can be adopted for wireless communications. I. INTRODUCTION Basically, intersymbol interference (ISI) in wireless communications increases bit error rate (BER) dramatically that cause to the poor transmission quality. Equalization is that the solution to combat this ISI effect. Many equalization techniques have been developed to equalize the ISI-disturbed signals for such a purpose at the receiver. In contrast, precoding is another well-known ISI cancellation technique in voice band or PSTN commu- nications that applies pre-equalization to the transmitted
