Energy Efficiency Optimization and Resource Allocation in Wireless Communication Systems (2017)
Abstract / truncated to 115 words
Nowadays, energy efficiency (EE) for wireless communications is becoming a main economical and societal challenge. This thesis studies resource allocation (RA) in EE optimized wireless communication systems for various system models. The main body of this thesis consists of three parts. In the first part, EE optimization is studied in multiple input multiple output (MIMO)-orthogonal frequency-division multiplexing (OFDM) systems. Two special scenarios are considered respectively in two chapters: rate-dependent circuit power and nonlinear distortion at the high power amplifier (HPA). For the first scenario, the condition of the rate-dependent circuit power such that the global optimal EE is guaranteed to be found is given. The impact of system parameters on EE are analyzed.
