Low Decoding Complexity Space-Time Block Codes For Point To Point MIMO Systems And Relay Networks
(2010-07-12)
It is well known that communication using multiple antennas provides high data rate and reliability. Coding across space and time is necessary to fully exploit the gains offered by multiple input multiple output (MIMO) ...
On The Best-m Feedback Scheme In OFDM Systems With Correlated Subchannels
(2017-07-07)
Orthogonal frequency division multiplexing (OFDM) in next generation wireless systems provides high downlink data rates by employing frequency-domain scheduling and rate adaptation at the base station (BS). However, in ...
Sequential Detection Based Cooperative Spectrum Sensing Algorithms For Cognitive Radio
(2011-07-11)
Cognitive radios are the radios which use spectrum licensed to other users. For this, they perform Radio Environment Analysis, identify the Spectral holes and then operate in those holes. We consider the problem of Spectrum ...
A Filterbank Precoding Framework For MIMO Frequency Selective Channels
(2011-02-28)
Wireless systems with multiple antennas at both the transmitter and receiver (MIMO systems) have been the focus of research in the recent past due to their ability to provide higher data rates and better reliability than ...
Sparse Bayesian Learning For Joint Channel Estimation Data Detection In OFDM Systems
(2018-08-30)
Bayesian approaches for sparse signal recovery have enjoyed a long-standing history in signal processing and machine learning literature. Among the Bayesian techniques, the expectation maximization based Sparse Bayesian ...
