- Description
- In this paper we propose two equalization methods for orthogonal frequency-division multiplexing (OFDM) modulation. These methods are intended to be alternatives to the known cyclic prefix equalization (CPE) method, and are derived using ideas from subband identification. The first proposed method is called subband equalization (SBE) and the second one is called enhanced cyclic prefix equalization (ECPE). The performance of different methods is compared in terms of bit error rate (BER) after equalization, convergence rate and computational cost in the presence of noise and fast fading. Both SBE and ECPE outperform the CPE in terms of BER and convergence rate. The SBE does not require the use of CP, and therefore saves channel capacity, but needs more computation than CPE, ECPE requires the use of CP, but its cost is compatible to that of CPE.
