System-Level Considerations
摘要
The demand for higher data rates is continuously rising as is the necessity for energy-efficient systems. The high complexity of communication systems characterized by many degrees of freedom makes it rather challenging to identify the optimal ways toward improvement. This chapter attempts to reveal the most essential high-level trade-offs in mm-Wave links, using Shannon’s capacity equation as a starting point. First, a qualitative discussion of the different system-level choices will be given. Then, the limitations in data rate and energy efficiency will be modeled in a quantitative manner, providing an overview of the primary performance bottlenecks in mm-Wave communication systems.
