Multi-Access MIMO Systems with Finite Rate Channel State Feedback

This paper characterizes the effect of finite rate channel state feedback on the sum rate of a multi-access multiple-input multiple-output (MIMO) system. We propose to control the users jointly, specifically, we first choose the users jointly and then select the corresponding beamforming vectors jointly. To quantify the sum rate, this paper introduces the composite Grassmann manifold and the co...

Capacity of MIMO System over TWDP Fading Channel with Channel State Information at the Transmitting Side

This paper investigates the capacity of an MIMO system over Two Wave Diffuse Power [TWDP] fading channels using well known water filling algorithm. The use of antenna arrays at transmitter and receiver sides of the wireless communication link (MIMO systems) can increase the channel capacity than the traditional single input single output [SISO] systems [9]-[15]. Here the channel capacity is stu...

Over-the-Air Computation in MIMO Multi-Access Channels: Beamforming and Channel Feedback

Future Internet-of-Things (IoT) networks are expected to wirelessly connect billions of sensors. It is impractical to collect data from the massive population of sensors using any traditional orthogonal multi-access scheme that leads to excessive latency. To tackle the challenge, a technique called over-theair computation (AirComp) was recently developed to enable a data-fusion to receive a des...

Trade-off between Feedback Load for the Channel State Information and System Performance in MIMO Communications

The performance of multiple-input multiple-output (MIMO) communication systems is greatly increased by having channel state information (CSI) at the transmitter. In systems with no channel reciprocity, a limited feedback link is used to send the CSI from the receiver to the transmitter. However, the resources for the feedback link come at the expense of resources from the communications link. T...

Cooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
