An assessment of spectrum efficiency for a microcellular land mobile radio system is presented by considering the desired signal as (fast) Rician fading with (slow) lognormal shadowing and co-channel interfering signals as uncorrelated (fast) Rayleigh fading superimposed over (slow) lognormal shadowing. Spectrum efficiency is defined in terms of reuse distance, Le., cluster size, traffic intens...

In this work we assess performance of multiple-input multiple-output (MIMO) antenna systems with space-time processing over a frequency-selective channel in presence of time-dispersive co-channel interference. We evaluate the performance of the conventional MIMO-decision-feedback equalizer (MIMO-DFE) receiver and also propose a low complexity receiver, based on the decoupled interference cancel...

The purpose of this paper is to investigate the use of combined spatial and temporal equalization, in particular for short training sequences. The motivation for combining spatial and temporal equalization is the existence of mul-tipath propagation and co-channel interference. Our main concern is to obtain good performance yet low complexity. We will suggest a low complexity algorithm utilizing...

This work was funded by IST project ANTIUM. Abstract This paper deals with the synchronization of a multi-antenna receiver for terrestrial digital video broadcasting (DVB-T) in the presence of strong co-channel interference. Two algorithms are proposed which exploit different features of the DVB-T signal. Both algorithms take advantage from the spatial diversity provided by the antenna array. T...

In this paper, a joint iterative power control and parallel interference cancellation (PIC) scheme is proposed for turbo coded uplink DS-CDMA systems to suppress the multiple access interference (MAI) from co-channel users and interantenna interference (IAI) from adjacent antennas of each user. Simulation results show that the proposed scheme could compensate for some channel fading effect thro...

This paper presents methods for synchronisation in the downlink of the FDD and TDD modes of a UMTS system. Space-time processing based on multiple receive antennas is used to suppress co-channel interference caused by other base stations. We develop a detection-based synchronisation procedure exploiting the structure of the respective UMTS mode, for which we present two alternative detection al...

In this paper, an adaptive co-channel interference suppression technique for multi-user MIMO MC DS/CDMA system is envisaged. MC DS/CDMA offers many advantages like flexibility, robustness, low PAPR and spectral efficiency. In spite of these advantages, performance of MC DS/CDMA system is greatly impaired by interference. Common interferences, which degrade the performance of the system, are MAI...

This application note discusses the different kinds of interference that operators will encounter in both current and new wireless environments. It introduces efficient and effective measurement techniques and instrument requirements for testing interference using modern highperformance spectrum analyzers such as Agilent FieldFox analyzers, which have the versatility and durability to make accu...

Communication in the presence of a priori known interference at the encoder has gained great interest because of its many practical applications. In this paper, additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is introduced as a new variant of such communication scenarios‎. First, it is shown that the additive Gaussian ch...

Digital modulation plays a significant role in efficient wireless communication. It allows the transmission of digital data via air on high frequency carrier waves. The worst case communication channel is usually in the urban environment where there are many obstacles. Due to the obstacles and reflectors, the transmitted signal arrives at the receiver from various directions over a multiplicity...
