Adaptive Transmission of Variable-Rate Data over a Fading Channel for Energy-Efficiency
Adaptive Transmission Variable-Rate Data Fading Channel Energy-Efficiency
2015/8/17
Adapting to a time-varying channel to maximize the average information rate for a given power constraint is a well-understood problem. Important studies (e.g., [I], [Z], [3]) have developed optimal ra...
High-speed Fading-free Direct Detection for DoubleSideband OFDM Signal via Block-wise Phase Switching
High-speed Fading-free Direct Detection Double Sideband OFDM Signal Block-wise Phase Switching
2014/11/6
We employ phase switching of either main-carrier or subcarriers of two consecutive signal blocks for double-sideband fading-free direct-detection (DD). In so doing, 40-Gb/s DDOOFDM is successfully rec...
