Relay networks have drawn extensive interest from the research community because they play an important role in enlarging the network coverage in wireless communications. In this proposed work the linear Gaussian relay problem is considered. In the context of the linear time-invariant (LTI) model, the issue of maximizing the rate in the linear Gaussian relay channel is expressed in the frequency domain, utilizing the Toeplitz distribution theorem. Given the additional assumption of feasible input spectra, the rate maximization challenge is transformed into a joint design problem for the source and relay filters, subject to two power Constraints are present, one at the source and another at the relay, and a viable solution to this problem is proposed based on the (adaptive) projected (sub)gradient approach. Numerical findings indicate that the suggested approach provides a significant advantage compared to the instantaneous amplify-and-forward (AF) scheme in inter-symbol interference (ISI) channels. Furthermore, the effectiveness of the AF scheme among one-tap relay filters is confirmed in flat-fading channels.
