Multipath Fading Channel Modeling and Performance Comparison of Wireless Channel Models
نویسندگان
چکیده
In this paper, we have proposed multipath fading channel simulation model for wireless communication. We have tested the model for sine wave and complex wave inputs. The effects of noise on fading and scattering property of the channel were tested. The results show that the BER performance is improved dramatically in low SNR than in high SNR. This is reasonable since at low SNR, white Gaussian noise dominate the BER error which can be improved by enhancing SNR while in high SNR, phase estimation error dominate the BER error which cannot be improved simply enhancing SNR. Next we have tested, analyzed and compared the performance of the channel models. The more accurate model is Rayleigh model which can be considered for developing multipath fading channel model.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

متن کاملModeling multipath fading channel dynamics for packet data performance analysis
The multipath fading channel modeling traditionally focuses on physical-level dynamics such as signal strength and bit error rate. In this paper we characterize multipath fading channel dynamics at the packet-level and analyze the corresponding data queueing performance in various environments. The integration of wireless channel modeling and data queueing analysis provides us a unique way to c...
متن کاملEnergy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...
