“…The presence of LoS has been confirmed through physical measurements for a number of applications, such as micro-cellular mobile and indoor radio [5]. In contrast to the Rayleigh case, there are few performance results for OC systems in these practical Rician fading conditions.…”

“…In contrast to the Rayleigh case, there are few performance results for OC systems in these practical Rician fading conditions. Moreover, of the results which are available, most restrict the number of interferers to be less than the number of receive antennas and/or employ a simplified interference-limited model [5][6][7][8], where the effect of thermal noise is ignored. Only recently have some results been presented in [9,10] which are not restricted to the interferencelimited model and allow for arbitrary number of interferers and receive antennas.…”

This paper analyzes the performance of multiuser optimum combining (OC) systems where the desired user undergoes Rician fading, and the received signals are corrupted by Rayleigh-faded interference and noise. We consider the SER and ergodic capacity in asymptotic SNR regimes, and derive new closed-form expressions for key performance parameters such as the diversity order, array gain, and wideband slope. These results clearly reveal the impact of the Rician K-factor, which is shown to be advantageous to performance in all cases.

“…The authors studied the performance of optimum combining (OC) and MRC diversity schemes [12,13] in wireless communication systems incorporating Rician fading and CCI. Novel mathematical methods were described [14][15][16] to express outage probability for a desired radio signal received from a mobile transmitter in the presence of multiple interfering signals with combined Lognormal and Rayleigh fading.…”

Transmission of information in wireless communications is subjected to multipath fading, adjacent channel interference, and adjacent cell interference. The aim of this paper is to study the analysis of maximal ratio combiner (MRC) in the presence of adjacent cell interference and adjacent channel Interference using outage probability. MRC is a well known signal processing technique in which the received signal at each antenna is weighted by their individual signal-to-interference plus-noise ratios and are coherently combined. Imperfect estimation of the desired user's channel fading coefficients will be analyzed and the channel fading coefficients will be assumed to be Gaussian distributed. The estimation error will be measured with the help of correlation coefficients between the true fading values and their estimates.Keywords Adjacent cell interference Á Adjacent channel interference Á Maximal ratio combiner Á Outage probability functions of MRC Á Probability density function Á Multipath fading

“…In particular, Shah and Haimovich [4] studied the MRC outage probability and bit error rate for independent identical distribution (i.i.d) Rayleigh/ i.i.d Rician model. The exact outage probability for the i.i.d Rician/Rayleigh case is given by Chayawan and Aalo in [6]. Moreover, The MRC outage probability for a constant envelope modulation scheme with CCI in Rayleigh fading environment was studied in [9].…”

This paper investigates the outage performance for a wireless system employing maximal ratio combining over various fading channels with Nakagami-m faded cochannel interferers (CCIs) and additive white Gaussian noise (AWGN). For the general case with unequal power CCIs and AWGN, it derives the exact closed-form expressions of the outage probability when the desired signal is subject to Rayleigh, Rician or Nakagami-m fading. Some numerical examples are given to illustrate the effects of various parameters on the system performance.
