High Speed Low Bit Error Rate Digital Audio Broadcasting System Using Parallel Concatenated Convolution Turbo Codes
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 3
Abstract
The major parameters to analyze the performance Digital Audio Broadcasting (DAB) system is Speed and Bit Error Rate. Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input and Multiple Output (MIMO) techniques combination gives 4 th Generation Long Term Evolution (LTE). Using multiple carriers in OFDM provides higher level of spectral efficiency as compared to Frequency Division Multiplexing (FDM). In OFDM because of loss of orthogonality between the subcarriers there is inter carrier interference (ICI) and inter symbol interference (ISI) and to overcome this problem use of cyclic prefixing (CP) is required, which uses 20% of available bandwidth. In this paper an OFDM application standard called Digital Audio Broadcasting (DAB) system model is implemented in Matlab/Simulink environment. The performance of this system over a channel perturbed by AWGN noise and Coded Orthogonal Frequency Division Multiplexing (COFDM) technique is studied in which convolution codes and turbo codes are employed and computed the resulting bit error rates (BER) then summarize the parallel concatenated convolution turbo codes is improves the performance of DAB.
