Massive deployment of low data rate Internet of things and eHealth devices that require high reliability motivates the development of practical precoding and user selection techniques. In this paper, we show that throughput and communications reliability can be improved by incorporating knowledge of modulation type in the design of the multiuser transmit precoder. The transmission of low data rate...
Emerging wireless technologies require the support for a massive number of low data rate battery operated devices. With this motivation, this paper employs widely linear processing in simultaneous wireless information and power transfer (SWIPT) systems. By considering the transmission of low-rate one-dimensionally modulated signals in the downlink of a SWIPT broadcast channel, a widely linear zero...
Motivated by the poor performance of the existing transmit beamforming methods in low signal to noise ratio regime, and assuming that the knowledge of the modulation type could result in a more intelligent design of beamformers, this paper proposes a transmit beamforming method based on the concept of minimum probability of error (MPE) beamforming. We calculate the error probability of each user in...
Motivated by power-limited uplink access, this paper proposes a receiver optimization for the uplink of a spatial multiple access scenario based on the concept of minimum probability of error (MPE) beamforming. Although MPE beamforming is shown to be more effective than the classical beamforming methods, it results in a non-convex and a highly nonlinear optimization problem. To resolve this problem,...
A novel receiver optimization for spatial multiple access scenario is studied in this paper where each user uses single antenna and multiple antenna array is used at the base station. To achieve space division multiple access, the newly introduced minimum probability of error (MPE) beamforming method is used instead of the conventional minimum mean square error (MMSE) beamforming. To increase the...
