摘要: Two multi-rate transmission schemes, multi-code (MC) and variable-spreading-length (VSL) code, for realizing multimedia communications on three types of OFDM-CDMA systems are proposed. We integrate them into a programmable structure such that the operation can be controlled adjusted by system parameters thus transceiver used in different without changing fundamental hardware software architecture, which serves trend software-radio future application.
