ABSTRACT
With the developments in technique, people are paying more attention to high speed communication, which has excellent prospects for the future. As is known, the next type of communication system rate can be up to 10 Gb/s. In this paper, communication quality measured by bit error rate is discussed. We will analyse the results of simulations. The probability density function is discussed and the divergence angle and transmission diameter are also analysed. We will further analyse the relationship between parameters can bit error rate. This can help us understand the character of high-speed communication performance.
