On statistical characterization of EESM effective SNR over frequency selective channels

Song, Hui January 2010 (has links)
With frequency selective fading, the SNRs of each sub-carrier would vary over the time and frequency. It would then cause fluctuations of the effective SNR. As the decision of MeS in LA is based on the effective SNR, the study of the statistical characterization of effective SNR over frequency selective fading channels would be very important, This problem forms the basis of investigation in this thesis. The methodology used in this thesis is generally divided into two parts. The first part is to investigate the method in obtaining the distribution of EESM over frequency selective fading channels. Such approach will be very helpful for the second part of the work which is to obtain the exact distribution of the EESM effective SNR for a specified fading model. In this case, Nakagami-m fading model is used. The choice of this model is based due to its simplicity and experimental consistency. One of the important features of the distribution is that the SNR of a signal under Nakagami fading is gamma distributed. Thus, in performance evaluation involving Nakagami fading, one can often rely on established results (in the statistics literature) of the gamma distribution. An important special case of the Nakagami distribution is the Rayleigh distribution, which arises in the situation of where the line-of-sight (LOS) component between the transmitter and the receiver is absent, i.e., when all of the received power stems from scattered components. The corresponding distribution for the SNR is the exponential distribution. The research in this thesis represents an effort to provide a statistical characterization of EESM effective SNR which has not appeared in any existing literatures. The goals of this thesis is to Characterize the statistics of EESM effective SNR over frequency selective channels. Obtain the distribution of EESM effective SNR over correlated Nakagami-m fading channels. Theoretically analyze the performance (Le. average SNR, outage probability and Symbol Error Rate (SER) etc.) of EESM over correlated Nakagami-m fading channels. Provide simple approximations to the proposed analytical results. Try to find extension and application of the results.
