Distributed antenna network (DAN) is a promising wireless network which can mitigate the impacts of distancedependent/shadowing losses and fading. Frequency-domain space-time block coded-joint transmit/receive diversity (FDSTBC-JTRD) is an antenna diversity technique which allows an arbitrary number of transmit antennas while keeping the coding rate constant and is suitable for the downlink tra...

In this paper, we enable the coexistence of multiple wireless body area networks (BANs) using a finite repeated non-cooperative game, in which BANs are rational players but act selfishly. A gametheoretic based transmit power control scheme employing a novel utility function is proposed to maximize each network’s packet delivery ratio (PDR) at low transmit power. The proposed utility function pe...

To reduce the transmit power while increasing a transmission data rate, authors proposed a wireless multihop virtual cellular network (VCN). Each multi-hop link needs to be allocated a different channel. This means that for the given total number of channels, as the number of hops increases, the number of channels available for each link reduces. However, the signal-to-interference plus noise p...

Blind adaptive multiuser detection for direct sequence code division multiple access (DS-CDMA) signals over static and time-varying intersymbol interference (ISI) limited channels is considered. Blind adaptive detectors must be robustified for ISI channels, when there is significant mismatch between the received signature vector and the transmitted code (assumed known at the receiver). A new lo...

This paper considers a wireless communication network consisting of multiple interfering multicast sessions. Different from a unicast system where each transmitter has only one receiver, in a multicast system, each transmitter has multiple receivers. It is a well known result for wireless unicast systems that the feasibility of an signal-to-interference-plus-noise power ratio (SINR) without pow...

We study the throughput capacity and transport capacity for both random and arbitrary wireless networks under Gaussian Channel model when all wireless nodes have the same constant transmission power P and the transmission rate is determined by Signal to Interference plus Noise Ratio (SINR). We consider networks with n wireless nodes {v1, v2, · · · , vn} (randomly or arbitrarily) distributed in ...

AB-STRACT In this paper, we consider the signal-to-interference plus noise ratio (SINR) performance of several beamforming algorithms, taking particular account of the contribution of sources correlated with the desired signal. In addition, we derive an optimal method that maximizes SINR by combining with the desired signal estimate any components of the interference/multipaths that are correla...

In the proposed system, the codebook vect...

We consider feedback design for the integration of multi-user MIMO in cellular mobile radio systems. Feedback is given by the mobile terminals, which report beam indices referring to a set of fixed pre-coding beams and corresponding signal to signal to interference and noise ratio (SINR) for different supported spatial transmission modes. The SINR feedback is quantized with a different number o...

APhased MIMO radar with full waveform diversity is proposed which divides the transmit array into overlapping subarrays in such a way that the number of subarrays are equal to the number of transmit antennas. Each subarray send sout a unique wave form towards the target of interest and thus provides a full waveform diversity, which results in the virtual extension of received array. This virtua...
