Performance evaluation of space codes using 16-QAM technique

This paper represents the main motive of error detection and correcting codes. These codes are used for efficient transnsmission of data from transmitter side and are used to efficiently decode the transmitted data at receiver side and thus causing significant reduction in BER. At the receiver side these codes provides efficient decoding by detecting the errors if any occurred while transmission through channel and after detection of error, these codes provides removal or correction of that error. This error detection and correction of errors occurred in original data is referred to as channel coding. Here in given paper comparative analysis of block codes:- hamming code, Bose Chaudhuri Hocquengham (BCH) code, Cyclic Redundancy Check (CRC) code and Reed Solomon (RS) code by using bit error rate(ber) V/s Eb/No performance using 16-QAM (Quadrature amplitude modulation) is done.
