On the Duality of MIMO Transceiver Designs With Bit Allocation
Chien-Chang Li,Yuan-Pei Lin +1 more
TL;DR: This paper derives the duality between bit rate maximization and power minimization for both the cases with and without integer constraint on bit allocation and develops an algorithm for finding the rate-maximizing transceiver with integer bit allocation using the solution of power-minimizing system.

Optimum ISI-Free DMT Systems with Integer Bitloading and Arbitrary Data Rates: When Does Orthonormality Suffice?
Xuejie Song,Soura Dasgupta +1 more
TL;DR: This paper relax both the high bit rate and the integer bitloading approximation, and provide sufficient conditions on the underlying modulation schemes for which orthonormal DMT remains optimum.

Resource allocation problems in communication and control systems
TL;DR: This thesis presents a proof for NP-hardness of the multiuser multicarrier bit loading problem, thereby formally justifying the search for suboptimal solutions in control and communication systems.

Multiuser OFDM with adaptive subcarrier, bit, and power allocation
TL;DR: The results show that the proposed algorithm outperforms multiuser OFDM systems with static time-division multiple access (TDMA) or frequency-divisionmultiple access (FDMA) techniques which employ fixed and predetermined time-slot or subcarrier allocation schemes.
