A Low-Complexity Bit-Loading Algorithm for OFDM Systems Under Spectral Mask Constraint

This letter aims to solve the power minimization problem for interference-free OFDM systems under achievable throughput and spectral mask constraints. To this end, we use a general analytic formula to yield an efficient initial bit vector, i.e., given a total number of bits, the total power use corr...
