PERFORMANCE OF BIT ERROR RATE OF CODED OFDM FOR DIGITAL AUDIO BROADCASTING BY UTILIZING CONVOLUTIONAL SYSTEMS UNDER DIFFERENT CHANNELS

In this paper we exhibit an investigation of Bit Error Rate (BER), for Digital Audio Broadcasting (DAB) framework, utilizing Coded OFDM with various channel coding plans. Examination is done for convolutional coded and turbo coded information in an Additive White Gaussian Channel (AWGN) in light of various imperative lengths and code generator polynomials utilized for coding. A relative study on the computational multifaceted nature is likewise done by applying an sound flag and measuring the information preparing time per outline, on PCs with various processor speeds. It is demonstrated that a coding increase of roughly 6 dB is accomplished utilizing turbo coding when contrasted with convolution coding, at an expense of higher computational multifaceted nature
