Abstract

Abstract In this paper, parallel turbo phase shift keying-trellis coded modulation (Turbo PSK-TCM) schemes are designed using recursive convolutional encoders over Galois field GF (2 N). These encoders are designed using the nonlinear left-circulate (LCIRC) function. The LCIRC function performs a bit left circulation over the representation word. An optimum 1-delay GF (2 N) recursive convolutional encoder scheme using LCIRC (RC-LCIRC) is proposed for PSK-TCM schemes. The minimum Euclidian distance is estimated for these ...
