High power amplifiers (HPA), used at transmission, add nonlinear impairments to the output signals. Through Constant envelope (CE) transmission, distortion in the signal can be avoided without wasting power on PA linearization. A more restricted form

Linear Transmit Precoding with Optimized Dithering

Implementation of 1-bit Digital-to-analog converters (DACs) at base station (BS) antennas reduces power consumption and hardware complexity for a downlink massive MIMO system while introducing non-linear impairments in the transmitted signal. Through

International audience; Linear precoders have been shown to perform reasonably well at low SNR when the basestation of a MIMO downlink employs one-bit digital-to-analog converters to quantize the pre-coder outputs. However, at medium-to-high SNRs, an

In the present work we have analysed the performance of a dual hop cooperative communication system. Multiple relays are taken for DF (Decode and Forward) relaying of signal from source to the destination over i.i.d. α - μ generalized fading channe

International audience; We present a mathematical analysis of linear precoders for downlink multiuser massive MIMO. In the scenario we consider, one-bit digital-to-analog converters are employed at the basestation antennas for mitigating power consum
