Multi-Carrier Techniques for Broadband Wireless Communications provides an accessible
introduction to OFDM-based systems from a signal processing perspective. The first part …

Underwater acoustic communications are limited by the following channel impairments: time
variability, narrow bandwidth, multipath, frequency selective fading and the Doppler effect …

Underwater acoustic channel (UAC) is featured as fast time-varying characteristic, and
challenges the transmission designs. To countermine the time variation effect, we propose …

This letter presents a new bit-loading algorithm for discrete multitone systems that converges
faster to the same bit allocation as the optimal discrete bit-filling and bit-removal methods …

This paper focuses on the problem of optimal bit and power allocation in linear periodically
time varying (LPTV) channels in broadband (BB) power line communication (PLC). Previous …

In this paper we present two resource allocations techniques in a visible light
communication network with overlapping coverage areas due to the use of access points …

This paper considers bit-loading algorithms to maximize throughput under total power and
spectral mask constraints in interference-free OFDM systems. The contribution is twofold …

Aiming at minimizing the transmit power of orthogonal frequency-division multiplexing
(OFDM) systems subject to the target data rate, the target bit error rate (BER), the maximum …

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 …
