Abstract
An adaptive wireless transmitting/receiving system combines an adaptive modulation and coding (AMC) technique and a transmit diversity CFD) technique. A channel state is periodically checked and a coding technique and a modulation technique that are most suitable to the checked channel state are applied to a system, to thereby remarkably enhance a quality of a receiving signal.
Claims23
An adaptive wireless transmitting/receiving apparatus comprising:
- a modulation and coding scheme (MCS) setting unit for periodically checking a state information of a receiving channel and setting an optimum modulation and coding scheme (MCS) level;
- a transmitting unit for processing information bits according to a coding technique and a modulation technique of the set MCS level, and transmitting the processed signal according to a predetermined transmit diversity (TD) technique;
- and
- a receiving unit for processing a received signal according to the MCS and TD technique, which have been set by the transmitting side.
