| Abstract | This paper is concerned with the evaluation of the block error probability P/sub e/ of a block modulation code by optimum or suboptimum soft-decision decoding for an AWGN channel. In the range D/sub L/ of low signal-to-noise ratios, it is feasible to evaluate P/sub e/ by simulation. In the range D/sub H/ of very high signal-to-noise ratios, tight upper bounds on P/sub e/ are available. However, in most cases, there remains a gap between D/sub L/ and D/sub H/, and the value P/sub e/ for signal-to-noise ratios in this gap may be of practical interest. In general, very small values of the block error probability are required. It is infeasible to evaluate a very small P/sub e/ simply by simulation. In this paper, the maximum-likelihood soft-decision decoding of a block modulation code for an AWGN channel is considered, and a new method of evaluating the block error probability P/sub e/ for a wide range of signal-to-noise ratios is presented. The evaluation of P/sub e/ is reduced to numerical computations and simulations on statistics with not very small mean value. Computation results for the block error probabilities of some block modulation codes are given. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
