Detailed spatial statistical models of the channels are derived and it is found that, even in highly non-line-of-sight environments, strong signals can be detected 100-200 m from potential cell sites, potentially with multiple clusters to support spatial multiplexing.

Results show that, even though the interuser channel is noisy, cooperation leads not only to an increase in capacity for both users but also to a more robust system, where users' achievable rates are less susceptible to channel variations.

Measurements and capacity studies are surveyed to assess mmW technology with a focus on small cell deployments in urban environments and it is shown that mmW systems can offer more than an order of magnitude increase in capacity over current state-of-the-art 4G cellular networks at current cell densities.

This work considers a general multiple-antenna network with multiple sources, multiple destinations, and multiple relays in terms of the diversity-multiplexing tradeoff (DMT), and finds DMT upper bounds and investigates the achievable performance of decode- and-forward (DF), and compress-and- forward (CF) protocols.

The current state of the art for wireless networks composed of energy harvesting nodes, starting from the information-theoretic performance limits to transmission scheduling policies and resource allocation, medium access, and networking issues are provided.
Low power analog-to-digital conversion in millimeter wave systems: Impact of resolution and bandwidth on performance

- 6 February 2015
Using an additive quantization noise model, the effect of analog-digital conversion (ADC) resolution and bandwidth on the achievable rate is investigated for a multi-antenna system under a receiver power constraint, demonstrating that there is a maximum bandwidth beyond which the achievable rates decreases.
Achievable Rates for the Gaussian Interference Relay Channel
The results show that the maximum rate sum is achieved when the relay helps the sources in the transmission of common messages only and the sources continue to transmit common information even when the interfering links can support much less rate than the direct links.

This work considers a Rayleigh fading wireless relay channel where communication is constrained by delay and average power limitations, and introduces opportunistic decode-and-forward (ODF) protocol which utilizes the relay depending on the channel state.
