Abstract :
An adaptive multi-code transmission technique with adaptive multilevel modulation for 2.4 GHz-band wireless LAN systems is proposed. Using this technique, simultaneously transmitted codes and modulation schemes adaptively changed according to the propagation conditions. Numerical results show that high-rate transmission and high immunity can be achieved.
