Abstract: The generalised model for multipath signal estimation is developed in this work with distinct optimal gain and receives diversity operation deployed in the wireless system. The presented modelling technique determines channel impulse response and complex fading factor for different multipath transmission elements. This study investigates the performance of radio signal propagation in Rayleigh distributed fading channels with antenna diversity at mobile receiver. For this purpose, several network attributes including the Bit Error Rate, Signal-to-Noise Ratio, average delay and Root-Mean-Square delay spread characterising the wireless communications efficacy are estimated for varying number of multipath scattered components. These quantitative parameters can be exploited to predict the channel conditions for successful data transmission in typical multipath scenarios. In contrast to previous related works, our proposed work effectively combines the influence of multiple propagation paths affected by fading, scattering and spatial receiver diversity principles for extensive data analysis in the specific wireless communication environment.
