  Abstract

In the communication systems that employ pilot-aided channel estimation techniques, pilot symbols are time­multiplexed with data symbols, and the number of pilot symbols is usually limited. It is known that PADD (pilot-aided decision-directed) approaches exhibit better bit-error ratio (BER) performance than PA (pilot-aided) estimation algorithms over fading channels, because they use both pilot and data symbols for channel estimation. In this paper, conventional PADD algorithms are analyzed and an improved PADD algorithm for pilot symbol­aided channel estimations is proposed. The performance of this algorithm is evaluated in Rayleigh fading environ­ments. Simulation results show that the proposed algorithm has better performance than conventional PADD algorithms.
