Bit-Error-Rate Simulation UsingMatlab

应用背景Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.关键技术主要说明了如何利用matlab对比特错误率进行仿真。从以下几个方面给予说明：采样信号的特点、发送信号模型、建立SNR、确定Eb、确定N0、计算噪声方差、加性噪声等，步骤非常详细，为差错控制编码进行BER仿真提供强有力的解释。
