Improvement of Extended Symbol-Aided Estimation for Rayleigh Fading Channels
Summary :
In this paper we present improved techniques for transmitting M-PSK signals in mobile radio environments. Conventionally an optimal linear combination of the observable fading at the pilot symbols has been used as estimations of all other fading. Recently, an improved technique was proposed by the authors which employs not only the pilot symbols but also the previously estimated fading values on data symbols to extract more information on fading channels. In this paper we present new methods by further improving the above method invented by the authors. The present methods utilize, instead of the estimated fading values on data symbols, the demodulator output normalized by the decided (decoded) data symbols to estimate the fading values in the current frame. We also show by computer simulations for BPSK system that the proposed estimation methods provide better performance than those of the conventional methods.
