Wireless cooperative relay is an efficient way in obtaining diversity in distributed manner, and it can also be used as a way in extending the cell coverage in cellular systems. In this paper, assuming receiver channel state information (CSI) only, the ergodic and outage capacity analysis are presented for amplify-and-forward (AF) multiple-input multiple-output(MIMO) relay channels deploying orthogonal...
In this paper, capacity performance analysis is presented for multiple-input multiple-output (MIMO) relay channels with transmit antenna selection and maximal-ratio combining receive (TAS/MRC) in amplify-and-forward (AF) relay networks operating over flat Rayleigh fading channels. Assuming that the source and destination are equipped with Ns and Nj antennas, respectively, and communicate with each...
Performance analysis is presented for multiple-input multiple-output (MIMO) relay channels with transmit antenna selection and maximal-ratio combining receive (TAS/MRC) in two-hop amplify-and-forward (AF) relay networks operating over flat Rayleigh fading channels, where the source and destination are equipped with Ns and Nj antennas, respectively, and communicate with each other with the help of...
We consider a multi-hop wireless sensor network in which a large number of sensor nodes are grouped into cooperative clusters. Multi-hop transmission is carried out between the source and the destination nodes by concatenating consecutive cluster-to-cluster hops. For each hop, both the transmit and the receive clusters can exploit node cooperation such that cooperative distributed multiple-input multiple-output...
In this paper, a framework to study the error performance of multiuser diversity in point-to-multipoint (PMP) MIMO transmit antenna selection networks is presented. Based on this framework, we derive the exact closed-form symbol error rate formula in terms of antenna selection gain, MIMO configurations, multiuser diversity and amount of fading gain to study the insight interaction between these factors...
This paper develops a framework to analyze the outage capacity of multiuser diversity in a multiuser MIMO transmit antenna selection with maximal-ratio combining (TAS/MRC) system. A closed-form expression of the system outage capacity is derived, through which we show how and with what characteristics the MIMO configurations, the number of users and the multiuser diversity affect the outage capacity...
Multiple-input and multiple-output (MIMO) system has captured considerably attention recently. In this paper, we present the analysis of multiuser scheduling in MIMO space-time block coding (STBC) system with imperfect channel estimation. Three commonly used multiuser scheduling methods - max throughput, round robin (RR) and proportional fair (PF) - are implemented to the MIMO STBC system and their...
Multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems can provide significant space diversity and combat multi-path fading, thus attracting increasing attention for the design of future broadband wireless communication systems. One enhancement technique commonly used in such systems is adaptive modulation and coding (AMC) for link adaptation. With AMC, the modulation...
