Power Optimized Single Relay Selection with an Improved Link-Adaptive-Regenerative Protocol

Table 1

Complexity of the proposed ILAR scheme and the contrast schemes.

Forwarding scheme	Pre-process at source node	Decoding/demodulation or transmission at Relay node	Combination at the destination
AF	No	N Multiplications	MRC detection
DF	1 Channel encoding	N Channel decoding	MRC detection
SDF	1 Channel encoding	N Channel decoding	MRC detection
Proposed ILAR	No	N ML-demodulation	MRC detection
