—Transmitter-based signal pre-processing is investigated for the two-dimensional (2-D) OFDM-CDMA (orthogonal frequency division multiplexing, code division multiple access) forwa...
Abstract--A common concept to mitigate the effects of spectrum scarcity is to allow opportunistic dynamic spectrum access (DSA) to licensed frequency bands. In this context, the li...

Abstract—This paper considers power and bandwidth allocation to maximize the end-to-end rate in a multihop wireless network. Assuming an orthogonal frequency division multiplexin...
Multiband orthogonal frequency-division multiplexing (MB-OFDM) systems employ frequencyhopping technology to achieve the capabilities of multiple access and frequency diversity. H...
— While a great number of space-time (ST) code and space-frequency (SF) code designs have been extensively studied for point-to-point single-user links and directly applied to ea...
