Method and System for Simulating a Noisy Communications Channel Based On a Cryptographic Function Implemented in FPGA or ASIC

A method of simulating communication channel noise comprising:

• generating, by a field programmable gate array (FPGA) or application specific integrated circuit (ASIC), a stream of uniformly distributed random variables using a cryptographic algorithm;
• applying a mathematical transform to the uniformly distributed random variables using the FPGA or ASIC to create a signal comprised of normally distributed random variables;
• adjusting a mean and variance of the signal using the FPGA or ASIC;
• outputting, by the FPGA or ASIC, an output noise signal;
• adding, by the FPGA or ASIC, I and Q samples of the output noise signal to I and Q symbols of a data carrier signal at complex baseband;
• modulating, using a modulator, the summed I and Q symbols to create a composite carrier signal;
• and
• upconverting using an upconverter, the composite carrier signal for transmission across a telecommunications channel to simulate a noisy telecommunications channel.
