DPSK performance for indoor wireless Rician fading channels
IEEE Transactions on Communications, 1994Indoor wireless channels which fade because of reflections from the building structure and the objects within the building have been experimentally found to fit either Rayleigh or Rician statistics. Digital communications performance has been calculated for these models, although in the Rician case numerical methods are typically employed.

Performance of MHPM in Rician and Rayleigh fading mobile channels
IEEE Transactions on Communications, 1997This paper evaluates the error probability of the rectangular frequency pulse multi-h modulation (MHPM) scheme in slowly-fading, frequency-nonselective or frequency-selective Rician and Rayleigh channels. The evaluation is performed with a method combining analysis and computer simulation.

On the design of universal receivers for nonselective Rician-fading channels
IEEE Transactions on Communications, 1994The purpose of this paper is to illustrate the issues involved in designing the demodulator portion of a universal receiver for unknown or time-varying channels by means of a specific example. We consider the class of nonselective Rician fading channels with additive white Gaussian noise.

Error Probability for Coherent Modulations in Rician Fading Channel
International Journal of Interdisciplinary Telecommunications and Networking, 2009Simple closed-form solutions for the average error rate of several coherent modulation schemes including square M-QAM, DBPSK and QPSK operating over slow flat Rician fading channel are derived. Starting from a novel unified expression of conditional error probability the error rates are analysed using PDF based approach.

GFDM/OQAM implementation under Rician fading channel
2016 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2016Future wireless applications demand a high data rate per user, low latency, spectral efficiency and high connection density. One of the contenders for 5G, Generalized Frequency Division Multiplexing (GFDM), seems to serve the next generation wireless needs due to its attractive properties when compared to the existing cyclic prefix orthogonal FDM (CP ...

Channel Inversion in MIMO Systems over Rician Fading
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010We examine the distribution of the per virtual-channel received signal-to-noise ratio over a multiple-input multiple-output channel modeled by a rank-2 non-central Wishart matrix. The exact probability density function is derived for all possible non-centrality matrices; and verified through simulation for selected systems.

Impact of correlated diversity branches in Rician fading channels
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005The effect of correlated branches on the performance of coherent maximum ratio combining (MRC) and non-coherent equal gain combining (EGC) diversity receivers over Rician fading channels is studied. The asymptotic error and outage probabilities for the MRC and EGC receivers with arbitrarily correlated branches for high average signal-to-noise ratios ...
