Title :
Non linear block equalizer for block data transmission system
Abstract :
This paper presents the development of a nonlinear block equalizer (NLBE) for the block transmission system (BTS) that is suitable for transmission of digital data over fading time-dispersive channels such as high signaling rate HF channel, mobile radio channel, indoor wireless etc. The optimum detection process for the BTS that has the lower bounds for the probability of error, is found to be computationally intensive for practical block sizes. The NLBE developed in this paper is a simple extension of the linear block equalizer (LBE) proposed earlier, and can be realized adaptively using simple equipment. The performance of the NLBE is compared with that of the LBE, and the optimum system for different values of the channel distortion. It is found that for severe amplitude distortions the performance of the NLBE is much better than that of the LBE and only slightly inferior to that of the optimum system.
