Abstract
In this paper, a new method is proposed to achieve a multi-class multirate fast frequency hopping code division multiple access system (FFH-CDMA) based on a novel code overlapping procedure. We investigate mainly the system architecture, and implementation. The first task is the basic building blocks of the transmitter-receiver architecture, which accomplishes our desired signal processing requirements without the need for complex frequency synthesizer. Based on the proposed block diagram we have built a prototype of the encoder-decoder using FPGA as it is easy to implement, allow high frequency achievement, and it is upgradeable.
