Digital Communication Over Fading Channels: A Unified Approach to Performance Analysis
TLDR
The book gives many numerical illustrations expressed in large collections of system performance curves, allowing the researchers or system designers to perform trade-off studies of the average bit error rate and symbol error rate. Expand
On the Energy Detection of Unknown Signals Over Fading Channels
This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-form expressions forExpand
Coded Communication over Fading Channels
In studying the performance of coded communications over memoryless channels (with or without fading), the results are given as upper bounds on the average bit error probability (BEP). In principle,Expand
End-to-end performance of transmission systems with relays over Rayleigh-fading channels
TLDR
End-to-end performance of two-hop wireless communication systems with nonregenerative relays over flat Rayleigh-fading channels is presented and average bit-error rate expressions for binary differential phase-shift keying, as well as outage probability formulas for noise limited systems are derived. Expand
Adaptive Modulation over Nakagami Fading Channels
TLDR
Results show that rate adaptation is the key to increasing link spectral efficiency and the impact of time delay on the BER of adaptive M-QAM. Expand
A new simple model for land mobile satellite channels: first- and second-order statistics
TLDR
A new shadowed Rice (1948) model for land mobile satellite channels, where the amplitude of the line-of-sight is characterized by the Nakagami distribution, provides a similar fit to the experimental data as the well-accepted Loo's (1985) model but with significantly less computational burden. Expand
Capacity of Rayleigh fading channels under different adaptive transmission and diversity-combining techniques
We study the Shannon capacity of adaptive transmission techniques in conjunction with diversity-combining. This capacity provides an upper bound on spectral efficiency using these techniques. WeExpand
A unified approach to the performance analysis of digital communication over generalized fading channels
Presented here is a unified approach to evaluating the error-rate performance of digital communication systems operating over a generalized fading channel. What enables the unification is theExpand
A performance study of dual-hop transmissions with fixed gain relays
TLDR
Numerical results show that dual-hop wireless communication systems equipped with non-regenerative fixed gain relays have a comparable performance to non-Regenerative systems with variable gain relay and that relay saturation of these systems results in a minimal loss in performance. Expand
