Novel accelerated simulation techniques for low bit error rate communication systems

Conventional simulation techniques are not suitable for modern low bit error rate communication systems, since significant computational power is required to achieve statistically significant results. Two novel simulation techniques are presented, which reduce the time required without affecting the performance. These are based on channel noise statistics, and generate error events without simulating a prohibitively large number of code words. This reduces the total number of code words that must be simulated, depending on the error correcting power of the code. The reduction in the simulation time required is two orders of magnitude, compared with conventional simulation techniques
