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