ABSTRACT

The process of changing some characteristics (e.g. amplitude, frequency or phase) of a carrier wave in accordance with the intensity of the signal is known as modulation. This process is needed to reduce practical antenna length, to increase operating range, and efficient radiation of an antenna. Generally this modulation involves amplitude modulation, frequency modulation, and phase modulation. Only this is not enough study in communication in deep we need more modulation sub classes such as PAM, QAM, PSK, BPSK etc which is useful in communication system . But those systems have some complexity and various relative disadvantages. Most powerful relative disadvantage is symbols error rate. So for less error free communication we need analysis PAM, QAM, PSK, and BPSK.
