To make data bandwidth changeable and suit for different communication situations, thereby improving the utilization rate of hardware, this paper designed a direct sequence spread spectrum module with variable bandwidth and could used in a variety of occasions based on m sequence code generator with configurable series. The programmable m sequence code generator create a number of different pseudorandom sequence using FPGA programmable features and do XOR operation with signals waiting transmit. There for, it can achieve the purpose of spread spectrum. As the series can be changed, this module could fit normal communication, communication experiment, or other communication area which need high security level.
