Title

ACHIEVING BETTER PERFORMANCE OF S-MMA ALGORITHM IN THE OFDM MODULATION

Pages

  9-17

Abstract

 Effective algorithms in modern digital communication systems provide a fundamental basis for increasing the efficiency of the application networks which are in many cases neither optimized nor very close to their practical limits. EQUALIZATIONs are one of the preferred methods for increasing the efficiency of application systems such as orthogonal frequency division multiplexing (OFDM). In this paper, we study the possibility of improving the OFDM modulation employing sliced multi-modulus algorithm (S-MMA) EQUALIZATION. We compare applying the least mean square (LMS), multi modulus algorithm (MMA) and S-MMA EQUALIZATIONs to the per tone EQUALIZATION in the OFDM modulation. The paper contribution lies in using the S-MMA technique, for weight adaptation, to decreasing the BER in the OFDM multicarrier modulation. For more efficiency, it is assumed that the channel impulse response is longer than the CYCLIC PREFIX (CP) length and as a result, the system will be more efficient but at the expense of the high intersymbol interference (ISI) impairment existing. Both analysis and simulations demonstrate better performance of the S-MMA compared to LMS and MMA algorithms, in standard channels with additive white Gaussian noise (AWGN) and ISI impairment simultanously.Therefore, the S-MMA EQUALIZATION is a good choice for high speed and real-time applications such as OFDM based systems.
