Amplify-and-Forward Cooperative Diversity for Green UWB-Based WBSNs
This paper proposes a novel green cooperative diversity technique based on suboptimal template-based ultra-wideband (UWB) wireless body sensor networks (WBSNs) using amplify-and-forward (AF) relays. In addition, it analyzes the bit-error-rate (BER) performance of the proposed nodes. The analysis is based on the moment-generating function (MGF) of the total signal-to-noise ratio (SNR) at the des...
متن کاملCooperative beamforming for OFDM-based amplify-and-forward relay networks
In this paper, we investigate the cooperative beamforming (BF) design problem for amplify-and-forward relay networks over frequency-selective channels. Orthogonal frequency division multiplexing (OFDM) transmission is employed to resist the multipath effects. We focus on the time-domain (TD) BF due to the lower implementation complexity and less feedback requirement from the destination to perf...
متن کاملOpportunistic nonorthogonal amplify-and-forward cooperative communications
Introduction: Cooperative communications [1] create diversity gains for network users with a single antenna. The classical cooperative scheme consists of two orthogonal time slots (TS): a broadcasting TS for a source (S) to transmit its signal to the intended destination (D), and a relaying TS for a relay (R) to retransmit S’s signal to D. There are amplify-and-forward (AF) and decode-and-forwa...
متن کاملAmplify and Forward Cooperative Diversity for Modified SV Model Based UWB Communication System
Cooperative diversity has emerged as a major technique of providing gains from spatial diversity to devices/terminals. While ultra-wideband (UWB) offers high information rates for wireless communication and sensor networks, the EIRP limits on UWB devices severely affects its coverage radius. In this paper, a low complexity cooperative diversity scheme for UWB channel is proposed. The scheme use...
متن کاملOn the Universality of Sequential Slotted Amplify and Forward Strategy in Cooperative Communications
While cooperative communication has many benefits and is expected to play an important role in future wireless networks, many challenges are still unsolved. Previous research has developed different relaying strategies for cooperative multiple access channels (CMA), cooperative multiple relay channels (CMR) and cooperative broadcast channels (CBC). However, there lacks a unifying strategy that ...
