In this paper, the performance analysis for a dual-hop Amplify-and-Forward relaying network is extended to the context of impulse radio ultra-wideband. Due to multiple accesses,the interference distribution is not Gaussian. We propose a symmetric α-stable model compatible with the impulsive nature due to its heavy tailed distribution. Taking advantage of the stability property, we develop...
In this paper, a Decode-and-Forward cooperative diversity scheme for performance enhancement is extended to the context of impulse radio ultra-wideband. Due to multiple accesses, the interference distribution is not Gaussian. We propose a symmetric α-stable model compatible with the impulsive nature due to its heavy tailed distribution. Taking advantage of the stability property, we develop the α-stable...
Indoor heterogeneous wireless sensor networks are considered in this letter. We analyze the power consumption for multihop communications with non-regenerative relays that can only amplify the received signal without decoding and coding it. Since sensor nodes are usually battery operated so that energy consumption is a crucial issue, we determine the minimal consumption in the different configurations...
