Abstract The peak-to-average power ratio (PAPR), commonly used to describe the amplitude variations of an OFDM (orthogonal frequency-division multiplex) signal, does not accurately reflect its impact on the system performance. This paper applies the

The increasing wireless device density and data rate in ISM bands used by, e.g., public institutions, industrial facilities and private households, have lead to substantial interference between wireless transmissions. The most famous representative s

Both windings and magnetic material cause losses in choke coils. For the efficient design of choke coils, a model of these losses is required where they are considered separately. In this paper, we focus solely on the winding loss. There are a number

In this paper, analytical rate expressions of interference alignment (IA) algorithms applied to the multiple-input multiple-output interference channel are derived in the large system limit. A large system analysis is performed by fixing the number o

The goal of the European ICT Project EARTH is to enhance energy efficiency of current LTE cellular networks by 50 percent, enabling operators to provide more extensive coverage, namely to less densely populated areas, while ensuring high levels of ef

Maximizing the sum capacity in the multiple-input multiple-output (MIMO) broadcast channel requires the use of dirty paper coding (DPC). However, practical implementations of DPC which are nearly optimum exhibit high computational complexity. As an a

Udgivelsesdato: June A random non-line-of-sight environment with stationary transmitter and receiver is considered. In such an environment movement of a scatterer will lead to perturbations of the otherwise static channel with a resulting Doppler spe

This paper covers the consideration of an iterative or turbo receiver where the nonlinear trellis-based detection of the interleaved and coded data bits is replaced by linear detection using the Wiener filter (WF), i.e., the optimal linear filter bas

This paper deals with iterative or turbo receivers where the maximum a posteriori detector has been replaced by a widely linear filter minimising the mean square error, that is the widely linear Wiener Filter (WF). In communication systems where the
