【Abstract】 This paper introduces the algorithm, architecture and realization of a configurable Gaussian noise generator. According to the Wallace method, we generate the normally distributed pseudorandom numbers directly by using their maximal-entropy properties. Control computer can perform a real-time configuration of the noise generator by the UART interface which is inside. Our design is coded in Verilog language. This system can be used in the truly wireless communication channel simulator by downloading to the FP-GA chip.更多还原
