Detecting errors and analyzing of Bit Error Rate for Digital audio broadcasting system, employing coded OFDM using CYCLIC REDUNDANCY CHECKER
In this paper, we present a study of detecting errors and Bit Error Rate (BER), for Digital Audio Broadcasting (DAB) system, employing Coded OFDM with a channel coding scheme. The analysis is carried out for cyclic redundancy checker bit in an Additive White Gaussian Channel (AWGN) based on different generator polynomials used for coding. A comparative study on the computational complexity is also done as Cyclic Redundancy checker is easy to implement, while the Turbo Codes are complex.
Keywords: Digital Audio Broadcasting (DAB), Orthogonal Frequency Division Multiplexing (OFDM), Additive White Gaussian Channel (AWGN) and Bit Error Rate (BER).
