ABSTRACT
Error control schemes are becoming increasingly important as the needs increase for very high rates of data transmission over inherently noisy channels (e.g. satellite and spread-spectrum communication). Forward error-correction is one means of improving channel performance, but at high data transmission rates very efficient decoder implementations are required. In this paper, we describe an efficient table-driven decoder for 1/2-rate nonsystematic convolutional codes. Various decoder implementation and performance issues are discussed.

An extensive search for good punctured rate-k/(k+1) recursive convolutional codes for serially concatenated convolutional codes
In many practical applications requiring variable-rate coding and/or high-rate coding for spectral efficiency, there is a need to employ high-rate convolutional codes (CC), either by themselves or in a parallel or serially concatenated scheme. For such ...
Finite-length rate-compatible LDPC codes: a novel puncturing scheme
In this paper, we study rate-compatible puncturing of finite-length low-density parity-check (LDPC) codes. We present a novel rate-compatible puncturing scheme that is easy to implement. Our scheme uses the idea that the degradation in performance is ...
Adaptive interleaver based on rate-compatible punctured convolutional codes
This letter focuses on the design of an adaptive Bit-Interleaved Coded Modulation (BICM) scheme for frequency selective slow fading channels where the transmitter has certain knowledge of the channel response. In particular, we consider the design of ...
