In this paper, the spectral efficiency of multiple-input multiple-output (MIMO) systems operating in multicell frequencyflat fading environments is studied, for situations in which co-channel interference is the dominant channel impairment instead of ambient noise. The following detectors are analyzed: the joint optimum detector, a group linear minimum-meansquare-error (MMSE) detector and its g...

We present the results of the performance evaluation of polarization-time coding and soft interference cancellation in multi-beam satellite systems a ected by co-channel interference in realistic setups. The standard of Broadband Global Area Network service (BGAN) has been considered as reference for the physical layer and realistic interference and channel models have been adopted. The work ha...

This paper presents some laboratory tests carried out to measure the BER degradation caused by an analogue PAL-G television interference on a COFDM 8K digital television signal. The tests made include co-channel and both upper and lower adjacent channel interference situations. Recently this year, the ITU-R has presented some protection ratios to be sought when planning DVB-T networks. The resu...

Performance analysis of switched-and-stay combining (SSC) and selection combining (SC) diversity receivers operating over correlated Nakagami-m fading channels in the presence correlated Nakagami-m distributed co-channel interference (CCI) is presented. Novel infinite series expressions are derived for the output signal to interference ratio's (SIR’s) probability density function (PDF) and cumu...

In this paper, we consider the mitigation of cochannel interference in Bluetooth by means of adaptive frequency hopping (FH). Prior to sending packets, the proposed scheme classifies whether the next FH channel is in use by other signals or not. It also periodically classifies channels occupied by the WLAN signal to change the hopping frequency. For fast classification of busy channels, it divi...

The Bell Labs Layered Space-Time (BLAST) architecture has been proposed to achieve high spectral efficiency on multi-input multi-output (MIMO) channels. Most studies of the BLAST algorithm consider spatially and temporally white noise and interference at the receiver. In this paper, we study channel estimation and data detection of a MIMO system under both spatially and temporally colored inter...
