Resumen
Abstract An efficient channel allocation algorithm is proposed for the Partial Block MCCDMA
system. Partial channel state information is used for determining the signal-to-noise
ratio of all frequency-block-bands. The prior is done to maximize the frequency-block-band
allocated to each block user. The proposed system improves the fairness among users and
allocates frequency-block-bands with better channel conditions to each block user; hence,
maximizes the system’s total throughput. The fairness of the proposed channel allocation
algorithm is analyzed by using Jain’s fairness index, and compared to that of the conventional
scheme.Moreover, the processing time needed to execute the proposed algorithm is calculated
and compared with the conventional and optimal algorithms.
