Summary:This paper introduces a hybrid forward-error correction/automatic
repeat-request (ARQ) system that employs rate compatible punctured turbo
(RCPT) codes to achieve enhanced throughput performance over a
nonstationary Gaussian channel. The proposed RCPT-ARQ system combines
the performance of turbo codes with the frugal use of incremental
redundancy inherent in the rate compatible punctured convolutional codes
of Hagenauer (1988). Moreover, this paper introduces the notion of
puncturing the systematic code symbols of a turbo code to maximize
throughput at signal-to-noise ratios (SNRs) of interest. The resulting
system provides both an efficient family of achievable code rates at
middle to high SNR and powerful low-rate error correction capability at
low SNR
