Webbcodes deﬁned on graphs which closely approach the channel capacity limit with feasible complexity (e.g., turbo codes [23], repeat-accumulate codes [1, 49], and low-density parity-check (LDPC) codes [124, 156]). Clearly, the desired bounds must not be subject to the union bound limitation, since for codes of large enough block lengths, these ...

Webbnoff bound together with the union bound may result in poor approximations to system performance (see, e.g., Section IV). The main challenge in determining the codeword PEP of space-time codes under maximum-likelihood detection is to average the Gaussian -function , where is a nonneg-ative random variable. This problem has been mainly studied WebbThe Gallager (1965) Bound (Cont.) † Usually impractical to evaluate in terms of basic features of par-ticular codes, but for example, orthogonal codes and the special case …

WebbFor regular decoding (without an erasure option), the random coding union bound of Polyanskiy et al. is improved by carefully taking ties (equal likelihood scores) into account. Webbmay be considered as an achievable bound for the compound channel as well as the AVC. III. FINITE BLOCKLENGTH ACHIEVABILITY BOUND The following theorem is our new achievability bound for the AVC. As we will illustrate below, this bound is analogous to the random coding union (RCU) bound for non-state channels, as derived in [3]. Theorem 1: …
