Etiketle | Özet: | This document analyzes the performance of an opportunistic wireless system on a Rice-type channel in the presence of co-channel interference. The analysis of the system is carried out in terms of the probability of bit error, considering that it operates on a channel with a Rice-type fading, thus establishing different threshold values and different mean values for different transmission scenarios. This allows to minimize errors in the reception of information. The results are obtained through Monte Carlo simulations, for which the MATLAB software was used, which allows to graphically show the probability of bit error. In addition, comparisons are made between the performance of an opportunistic system and an ordinary system. The results determine the operating efficiency of the system by varying the values of the interference signal ratio. Thus, it was evidenced that an opportunistic transmission is more efficient than an ordinary transmission, since opportunistic transmission mitigates the undesirable effects of fading and in turn also mitigates interference, since there are periods of non-transmission of interfering users, which makes the power of the interfering signal is reduced. Therefore, the proposal analyzed in this work allows to improve the performance of the system and with this to provide an effective and efficient solution to the transmission of data within a Rice-type channel. |
