The effect of channel resolution on compressed sensing based Ultra-Wideband channel estimation [Kanal çözünürlü?ünün sıkıştırılmış algılama tabanlı ultra geni?ş bantlı kanal kesti?ri?mi?ne etki?si?]
(2011)
Ultra short pulses are transmitted in Ultra-Wideband (UWB) communications. As a result of this pulses at the receiver can be resolved individually due to the sparse structure of the channel. Due to these properties the UWB ...
Achievable Performance of Bayesian Compressive Sensing Based Spectrum Sensing
(IEEE, 2014)
In wideband spectrum sensing compressive sensing approaches have been used at the receiver side to decrease the sampling rate if the wideband signal can be represented as sparse in a given domain. While most studies consider ...
The Effect of Codebook Design on the Conventional SCMA System Performance
(IEEE, 2020)
In 4G systems, Orthogonal Frequency-Division Multiple Access (OFDMA) has been used conventionally for multiple access purposes. This technique has low spectral efficiency since it allocates the resources orthogonally to ...
Enerji Verimli İletişim Sistemlerinin Tasarımı için Sıkıştırılmış Algılama Tabanlı Yaklaşımlar
(2016)
Sıkıstırılmıs Algılama (Compressed Sensing, CS) teorisi, isaretin seyrek bölgede tanımlanabildigi durumlarda Nyquist hızından çok daha düsük hızlarda örneklenen isaretin basarılı bir sekilde geri kazanılabilecegi gerçegine ...
