A Mixture Gamma Distribution to Model the SNR of Wireless Channels
Composite fading (i.e., multipath fading and shadowing together) has increasingly been analyzed by means of the K channel and related models. Nevertheless, these models do have computational andExpand

Probability of error calculation of OFDM systems with frequency offset
Orthogonal frequency-division multiplexing (OFDM) is sensitive to the carrier frequency offset (CFO), which destroys orthogonality and causes intercarrier interference (ICI), Previously, two methodsExpand

Energy Detection Based Cooperative Spectrum Sensing in Cognitive Radio Networks
Detection performance of an energy detector used for cooperative spectrum sensing in a cognitive radio network is investigated over channels with both multipath fading and shadowing. The analysisExpand

SLM and PTS peak-power reduction of OFDM signals without side information
Selected mapping (SLM) and partial transmit sequence (PTS) are well-known techniques for peak-power reduction in orthogonal frequency-division multiplexing (OFDM). We derive a simplified maximumExpand

Equal-gain diversity receiver performance in wireless channels
Performance analysis of equal-gain combining (EGC) diversity systems is notoriously difficult only more so given that the closed-form probability density function (PDF) of the EGC output is onlyExpand

Spectrum Sharing in Wireless Networks via QoS-Aware Secondary Multicast Beamforming
Secondary spectrum usage has the potential to considerably increase spectrum utilization. In this paper, quality-of-service (QoS)-aware spectrum underlay of a secondary multicast network isExpand

An efficient generalized sphere decoder for rank-deficient MIMO systems
We derive a generalized sphere decoder (GSD) for rank-deficient multiple input multiple output (MIMO) systems using N transmit antennas and M receive antennas. This problem arises when N>M or whenExpand

Distribution functions of selection combiner output in equally correlated Rayleigh, Rician, and Nakagami-m fading channels
We develop a novel approach to derive the cumulative distribution functions (cdfs) of the selection-combining (SC) output signal-to-noise ratio (SNR) in equally correlated Rayleigh, Ricean, andExpand

Error rates for Nakagami-m fading multichannel reception of binary and M-ary signals
This paper derives new closed-form formulas for the error probabilities of single and multichannel communications in Rayleigh and Nakagami-m (1960) fading. Closed-form solutions to three genericExpand

A PAPR Reduction Method Based on Artificial Bee Colony Algorithm for OFDM Signals
One of the major drawbacks of orthogonal frequency division multiplexing (OFDM) signals is the high peak to average power ratio (PAPR) of the transmitted signal. Many PAPR reduction techniques haveExpand
