Convolutional Code Performance in the Rician Fading Channel

IEEE Transactions on Communications, 1976
The performance of short constraint length convolutional codes in conjunction with binary phase-shift keyed (BPSK) modulation and Viterbi maximum likelihood decoding on the classical Rician fading channel is examined in detail. Primary interest is in the bit error probability performance as a function of E_{b}/N_{0} parameterized by the fading channel ...

A BER Analysis of NOMA on Rician Fading Channels

2020 IEEE Latin-American Conference on Communications (LATINCOM), 2020
Non-Orthogonal Multiple Access (NOMA) has been a hot research topic over the past years. The general trend in the NOMA literature is the so-called Power-Domain NOMA (PD-NOMA), which requires a strong power imbalance at the receiver between the superposed signals.

MIMO capacity results for Rician fading channels

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
The capacity of a multiple antenna system in Rician fading is considered under the assumption that channel state information (CSI) is available only at the receiver and that the transmitter has knowledge of the statistical properties of the fading process though not the instantaneous CSI.

Postdetection switch-and-stay diversity in rician fading

IEEE Wireless Communications and Networking Conference, 2005, 2005
Recent work has examined the performance of dual branch postdetection switch-and-stay combining (SSC) for noncoherent binary orthogonal frequency-shift keying (BFSK) and noncoherent M-ary orthogonal frequency-shift keying (MFSK) operating in the presence of slow, flat fading modeled by Rayleigh, Nakagami-m, and Rician distributions.

Approximation to the Capacity of Rician Fading MIMO Channels

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
In this paper, the capacity of multiple-input multiple-output (MIMO) systems over a Rician fading channel is evaluated. We show that the capacity of MIMO Rician channels can be well approximated by that of correlated MIMO Rayleigh channels. We take the Rician channel with rank-1 mean matrices as an example, the asymptotic capacities at low and high ...

Outage Probability of Rician Fading Relay Channels

MILCOM 2006, 2006
In this paper, we consider the decode-and-forward (DF) relay network system over Rician fading channels. We derive an analytical expression for the outage probability of the highest achievable information rate of the system, which can be evaluated by employing standard numerical techniques. We also obtain some simple but tight lower and upper bounds on

A review of selection combining receivers over correlated Rician fading

, 2019
Selection combiner output (SCO) cumulative distribution functions (cdfs) of multivariate equally-correlated and exponentially-correlated (e.c.) Rician, and other correlated fading environments for positive channel correlation coefficients are rigorously ...

Turbo code performance on Rician fading channels

1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003
The performance of turbo codes on frequency non-selective slow Rician fading channels is considered. The analytical average upper bounds of turbo code performance over the channels with independent fading are derived. Furthermore, we developed a decoding metric for fading channels and log-likelihood ratios and extrinsic information for maximum a ...

Predetection Switched Combining in Correlated Rician Fading

IEEE Transactions on Wireless Communications, 2007
The performance of dual-branch predetection switch-and-stay combining (SSC) in correlated Rician fading is considered in conjunction with several modulation formats. Analytical expressions are derived for the average symbol error rate (SER) of predetection SSC in correlated Rician fading. Switching thresholds that minimize the average SER are obtained.

Performance of decorrelating receivers in multipath Rician fading channels

IEEE Transactions on Wireless Communications, 2005
This letter focuses on the performance analysis of the decorrelating receiver in multipath Rician faded CDMA channels. M-ary QAM scheme is employed to improve the spectral efficiency. Approximate expressions are first derived for the two performance indexes: the average symbol error rate (SER) and the average bit error rate (BER) when the decorrelating-
