Generalized Compute-Compress-and-Forward
Compute-and-forward (CF) harnesses interference in wireless communications by exploiting structured coding. The key idea of CF is to compute integer combinations of codewords from multiple source nodes, rather than to decode individual codewords by treating others as noise. Compute-compress-and-forward (CCF) can further enhance the network performance by introducing compression operations at re...
متن کاملSuccessive Compute-and-Forward
In prior work, we proposed the compute-andforward framework for sending linear combinations of messages to relays. In this note, we extend the notion of successive interference cancellation to the compute-and-forward setting. We find that once a relay has decoded a linear combination, it can mix it with its channel output to create a new effective channel output. The resulting effective channel...
متن کاملReceiver Combining Compute-and-Forward
In this work, we present a generalized compute-and-forward scheme for the single input multiple output (SIMO) channels. The proposed receiver combining compute-and-forward is well-suited to settings where a single receiver is equipped with multiple antennas. We show that combining channel outputs in a specific way makes the effective channel more suitable for decoding successive linear combinat...
متن کاملCompress-forward Relaying over Parallel Gaussian Channels
We propose a compress-forward (CF) strategy for relaying over parallel Gaussian channels. The proposed CF strategy compresses received signals at the relay under a constraint on the product of their allowable distortions and forwards them to the destination over all subchannels. Power allocation over all subchannels at both the source and the relay and bit allocation for compressing received si...
متن کاملAsymmetric Compute-and-Forward with CSIT
We present a modified compute-and-forward scheme which utilizes Channel State Information at the Transmitters (CSIT) in a natural way. The modified scheme allows different users to have different coding rates, and use CSIT to achieve larger rate region. This idea is applicable to all systems which use the compute-and-forward technique and can be arbitrarily better than the regular scheme in som...
