Abstract

Multi-code CDMA system provides high speed and variable rate services with different quality requirements. Since envelope fluctuation of the multi-code signal is large, the system requires highly linear power amplifier. In this paper, we propose binary level multi-code pulse width (PW-) CDMA system. In the system, linear sum of orthogonal codes is truncated and pulse width modulated. The transmitting signal has constant envelope, and the receiver structure is very simple. Hence, the proposed system is appropriate for low cost high data rate applications. We investigate the bit error performance of the binary level multi-code PW-CDMA system.
