Iterative Group-by-Group Bit-Loading Algorithms for OFDM Systems

In a recent paper, we proposed group-by-group bit filling (GBF) and group-by-group bit removal (GBR) to boost the efficiency of bit loading. Generally, GBF/GBR converges to a suboptimal bit-allocation profile (BAP), and thus, a supplementary greedy bit-filling/bit-removal procedure is required to co...
