Bit-Error-Rate (BER) Simulation Using MATLAB

This paper introduce the Bit error rate, (BER) simulation using Mat lab. Bit error rate, (BER) is a key parameter that is used in assessing systems that transmit digital data from one location to another. Systems for which bit error rate, is applicable include radio data links as well as fiber optic data systems, Ethernet, or any system that transmits data over a network of some form where noise, interference, and phase jitter may cause quality degradation of the digital signal. Mat lab 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 with Mat lab is very simple, but does require some prerequisite
