Abstract We propose an improved Soft Forwarding (SF) protocol which is based on the symbol-by-symbol detection at the relay node, unlike in the conventional relaying strategy which implements a bit-by-bit signal analysis at the relay node. A relay node which is typically acts like a repeater can avoid unnecessary computation complexity and above all, is resource efficient if compared to the baseline SF [1]-[2]. The proposed strategy is implemented based on Maximum Likelihood Detector (MLD) criterion. We simplify the MLD rule to one-dimensional real space such that all metric values are compared in a straight line making the ML performance analysis tractable. Simulations have shown that the proposed schemes outperform the conventional schemes in error rate performance.
