The 12th International Symposium on Wireless Personal Multimedia Communications (WPMC 2009) A COMPARATIVE STUDY ON THE TRANSMIT POWER CONTROL SCHEMES FOR MULTI-USER MIMO SYSTEM

چکیده
The capacity performance of multi-user multiple input multiple output (MIMO) in a cellular system is of a great interest. This paper presents a comparative study on the transmit power control (TPC) schemes for uplink multi-user MIMO systems. Two kinds of TPC schemes, namely, zero-outage TPC and minimum interference TPC, are considered. The capacities of both schemes are theoretically analyzed and then compared with the capacity of the system without TPC by numerical results.

To support rate allocation schemes for wireless ad hoc networks at the MAC layer, a cross-layer MAC protocol is proposed in this paper to coordinate transmissions among flows and guarantee their allocated rates. Two different algorithms are implemented in this protocol: the first one is able to support an arbitrary bandwidth allocation scheme but has a longer convergence time, while the second ...

Multi-carrier code division multiple access (MC-CDMA) is a promising multiple access scheme. An extremely high spectrum efficient transmission technique is required in future wireless communication systems. The use of multiple-input multiple-output (MIMO) space division multiplexing (SDM) is essential to achieve a very high speed data transmission with a limited bandwidth. In this paper, we der...

In this paper, a low complexity subcarrier allocation scheme is proposed for multiuser MIMO-multiuser OFDM systems with zero-forcing beamforming (ZFBF) to minimize the total transmit power satisfying given target data rates of users. The ZFBF for multiuser MIMO makes multiple spatial channels by removing multiuser interference and the subcarrier allocation can be performed over spatial and freq...

This paper proposes a method for initiating IP-based peer-to-peer (P2P) communication sessions in cases where the target of the initial communication attempt is a mobile device. Mobile P2P networking poses certain problems: a battery-powered device may not always keep its network interfaces on for IP communications due to battery life issues, and mobile hosts are typically also behind a NAT tha...

We present a simple combining receiver for a dual-diversity wireless relay network. The main concern of the paper is to face the trade-off between performance and complexity. The receiver focuses on signal-to-noise ratio (SNR) monitoring and selects dynamically between selection combining (SC) and equal gain combining (EGC) depending on the SNR ratio of the two received branches. It is shown th...
