摘要
A system with one or more base stations is described having an outer code encoder to generate an outer code based, at least in part, on a plurality of data elements using an (N,K) Reed-Solomon (RS) code over FG(2m). N represents the length of the RS code, K the length of a message, and m the length of a symbol. The system includes an inner code encoder to generate an inner code based, at least partly, on the outer code using a (m+1, m) parity-check code. The system includes a radio frequency transmitter to transmit a signal based, at least in part, on the inner code and includes a plurality of customer premises equipment (CPE) stations. The CPE stations have a radio frequency receiver to receive the signal and a decoder to decode at least a portion of the data elements based, at least partly, on the received signal.
