Abstract

Adaptive techniques are becoming demand of almost every modern communication system. In this technique, transmission parameters are adapted in such a way that the overall throughput of the system is maximized and certain constraints are satisfied. In this paper a similar constrained optimization problem is focused and a fuzzy rule based system (FRBS) is proposed for its solution. The transmission parameters being optimized are practical channel code, modulation symbol and the transmit power. FRBS suggests the optimal code rate and modulation symbol while water-filling algorithm suggests the power vector according to channel conditions at Orthogonal Frequency Division Multiplexing (OFDM) sub-channels, so that throughput can be maximized while bit error rate (BER) and power remain constrained. Comparison of two channel codes namely Product codes and Convolutional code is given while Quadrature Amplitude Modulation (QAM) as Modulation scheme is used under supervision of FRBS. Comparison of both schemes is shown by simulations
