Nowadays, the source localization has been widely applied for wireless sensor networks. The Gaussian mixture model has been adopted for maximum-likelihood (ML) source localization ...
— In this paper, distributed double-differential coding is proposed to avoid the problem of carrier offsets in amplify and forward protocol based cooperative network with two rel...
—In this paper, we propose a novel channel estimation scheme for the broadcast phase of the newly invented twoway relaying technique. Instead of using pilot sequences, we exploit...

−A class of combinatorial structures, called absorbing sets, strongly influences the performance of low-density paritycheck (LDPC) decoders at low error rates. Past experiments h...
—Conflict free spectrum allocation for secondary users in cognitive networks is a challenging problem, since the accessible spectrum is shared among users. The problem becomes to...
