In this paper, we present rate-compatible systematic repeat-accumulate (RA) codes for the additive white Gaussian noise (AWGN) channel. The systematic form is used because of the higher degree parity checks we require in the code. We show that very high code rates can be attained with good performance through our puncturing schemes. Although RA codes are(More)
In present day wireless applications, especially for time-varying channels, we require flexible coding schemes that utilize a minimum of bandwidth and can support different code rates. In addition, we require coding schemes that are simple in terms of complexity but give good performance. Recently a special class of turbo-like codes called repeat accumulate(More)
