Performance Analysis Of BPSK And QAM Modulation Schemes Using BCH Encoding Over Rayleigh Fading Channel

Abstract

Everybody has to communicate with each other so do computers, it is a necessary phenomenon for
exchange of information. Data is one of the most important entities in today's world, thus data reliability is of utmost
importance. The data exchanged between computers is sent over various communication channels, which can induce
noise in the data thus rendering data unreliable and inconsistent. The number of errors introduced in the data depends
on the encoding scheme, the communication channel being used and also the modulation scheme. Various encoding
schemes, communication channels and modulation schemes are used for data transmission, each of these schemes have
their advantages and disadvantages depending on the scenario. In this paper performance BPSK and QAM modulation
is compared using BCH encoding scheme over Rayleigh fading channel and the result so produced is presented in terms
of BER.
