WebDec 31, 2024 · The fast fading model is the Jakes spectrum and the channel coding is a convolutional encoder with a code ... This process is repeated until the algorithm completes its forward search through the trellis and reaches the termination ... Lee, K.T.; Cho, K.R. Convolutional turbo coded OFDM/TDD mobile communication system for ... WebThe problem is slightly more difficult in the case of a recursive code. Nevertheless, the trellis termination can be achieved by injecting zero bits at the input of the shift register, as shown in Figure 12 for the RSC encoder of Figure 9. For turbo codes, the trellis of one or both component codes can be terminated using tail bits.

Web[9]. Additional reports on trellis termination for Turbo codes are found in, among others, [10], [11]. The performance of trellis termination methods are, to various extents, dependent on the particular interleaver used in the Turbo encoder – a fact rarely acknowledged in the literature. This dependency is the result of interleaver edge ... WebNov 1, 2012 · Performance of a turbo code without trellis termination and the turbo code with its first trellis terminated is compared.
