SAFNAQ, an Algorithm for Transmission Power Allocation in MCCDMA
A power allocation algorithm for MC-CDMA communication systems is proposed. There are many algorithms of power allocation in MC-CDMA, e.g., Frequency Domain Power allocation Algorithm (FDPA), Time Domain Power allocation Algorithm (TDPA) and Eigenvector Based Power allocation Algorithm (EBPA) etc., available in literature. The FDPA algorithm uniformly allocates power to some adaptively chosen strongest sub-carriers and all other deeply faded sub-carriers are shut off. In TDPA, the power adaptation is considered so that the desired signal strength at MRC receiver maintains at a fixed level. The EBPA algorithm allocates power in accordance with a power balance vector.
