Improved Polar selective decoding and forwarding cooperation

Dianxin kexue, 2020
An improved Polar selective decoding and forwarding (IPSDF) scheme based on cooperative threshold de-cision was proposed.Firstly,a new construction of Polar codes according to the fading channel state information (CSI) was proposed.Then,a relay with best CSI was selected from the candidate relay set as the best relay.In addition,the proposed Polar ...

Rate Maximization of Decode-and-Forward Relaying Systems with RF Energy Harvesting

, 2015
We consider a three-node decode-and-forward (DF) half-duplex relaying system, where the source first harvests RF energy from the relay, and then uses this energy to transmit information to the destination via the relay.
