Abstract
The growing number of mobile stations requires relaying protocols that can efficiently transmit large volumes of data with minimal computational complexity. Systems that combine joint symbol and channel estimation with Amplify-and-Forward Multiway Relay (MWR) systems provide a highly effective solution to this problem. Thus, this study introduces a new Nested PARAFAC-based MWR system model as its primary contribution. Then, a non-iterative semi-blind receiver is designed to allow simultaneous estimation of symbols and channels. This computationally efficient approach is validated using Monte Carlo computational simulations, showing that the proposed receiver can achieve lower bit error rate values at lower computational complexity than some of its state-of-the-art competitors.
