Multiple antenna systems are promising architectures for overcoming the effects of multi-path interference and increasing the spectrum efficiency. Capacity increases promised by MIMO systems mostly depend on the spatial correlation properties of the radio channels. This letter investigates the performance of multiple-input and multiple-output (MIMO) antenna arrays systems including MIMO space-time...
Fractionally spaced Rake (FSRake) reception is proposed for non-coherent direct sequence ultra wideband (DS-UWB) wireless communication systems. In the FSRake reception, output signal of the pulse matched filter is sampled with a faster sampling rate than the chip rate of DS-UWB signal. Computer simulation is conducted to evaluate the performance of FSRake receiver in DS-UWB wireless system with M-ary...

Multiple access analysis is presented for pulsed direct sequence (DS) and hybrid DS time hopping (DS/TH) ultra-wideband (UWB) communications considering a Saleh-Valenzuela type clustered frequency selective Nakagami fading channel. A general analytical framework is developed for modeling the multiple access interference (MAI) in low-duty systems that is substantially complicated than analysis of more...
In this paper, we investigate the spatial fading correlation and symbol error rate (SER) performance of M-ray phase shift keying (MPSK) with maximal ratio combining (MRC) for a circular antenna array for two types of angle of arrival (AOA) energy distributions: a uniform AOA energy distribution and a Gaussian AOA energy distribution. The spatial fading correlation and SER performance of a circular...
Multiple antenna arrays are promising architectures for overcoming the effects of multipath interference and increasing the spectrum efficiency. In order to be able to investigate these systems, in this article, we derive generalized spatial correlation equations of a circular antenna array for two types of angular energy distributions: a Gaussian angle distribution, and uniform angular distribution...
