A REVIEW ON BPSK MODULATION TECHNIQUES AND DEMODULATION SCHEMES

Abstract

High data-rate is desirable in many recent wireless multimedia applications. Modulation techniques have concerned increasing attention in optical wireless communications. In this paper, we implemented a Binary Phase Shift Keying (BPSK) modulator and demodulator for a digital communication. This is a review paper, in which we discussed about the basic components of Digital Communication process and the various techniques of Transmission and Receiving of Digital data bits. Since, in today's world, error-free data transmission with proper or approximate accurate Synchronization covers a wide area of scientific researches, we put concern about the transmission of error free data or less error containing data from the transmitter end to the receiver end but using various modulation techniques like Hamming Code, Cyclic Code, BCH Codes, Reed-Solomon Codes and others. As the PSK output signal is in suspended strip line, two BPSK modulators can be easily combined together to work as QPSK modulator.
