Performance Analysis and Formulation of Turbo Coded OFDM over Rayleigh & Rician Fading Channel
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2012, Vol 2, Issue 3
Abstract
In wireless communication, to attain high throughput and better transmission quality, there is a need of better system design . Orthogonal Frequency Division Multiplexing (OFDM) is a techniques for parallel transmission. The performance of OFDM can be improved by using some kind of channel coding. This form of OFDM is called coded-OFDM (COFDM). In this paper Turbo code is used as channel coding with OFDM, called Turbo coded OFDM .This paper compares the performance of Turbo coded OFDM using binary phase shift keying (BPSK) , Quadrature Phase Shift Keying (QPSK) , Quadrature Amplitude Modulation (QAM) modulation technique for different Rayleigh and Rician fading channel . Results is formulated that a combination fading channel and modulation technique gives better performance.
