Optimum Mode-Switching Assisted Adaptive Modulation

, 2001
Adaptive modulation techniques combat fading by employing a suitable modulation mode depending on the instantaneous channel conditions for improving the Bit Error Rate (BER) performance or the average through-put.

Optimum Mode-Switching-Assisted Constant-Power Single- and Multicarrier Adaptive Modulation

, 2003
A set of optimum mode-switching levels is derived for a generic constant-power adaptive-modulation scheme based on a closed-form expression of the average bit error ratio (BER) and the average bits-per-symbol (BPS) throughput of the adaptive-modulation ...

Cross-phase modulation in rubidium-87 [PDF]

, 2009
This thesis explores the theoretical foundations of cross-phase modulation (XPM) between optical fields in the N-configuration atom. This is the process by which the refractive index experienced by one field can be modulated by controlling the intensity

Low-Complexity Near-Optimum Multiple-Symbol Differential Detection of DAPSK Based on Iterative Amplitude/Phase Processing

Differentially encoded and non-coherently detected transceivers exhibit a low complexity, since they dispense with complex channel estimation. In pursuit of high bandwidth efficiency, differential amplitude and phase shift keying (DAPSK) was devised ...

Alternating-phase focusing with amplitude modulation

, 1993
We have previously developed a model of alternating-phase focusing (APF) applicable to ion linacs comprised of short independently controlled cavities.
