considerably. However, as discussed in Sect. 2.3, for medium-long-range UAC, the propagation time of the feedback signal could be much larger than the coherence time and therefore nullify the instantaneous CSI feedback. In this chapter, statistical CSI is considered for the design of the medium-lon

Introduction, For the environmental monitoring purpose, UWASN can perform real-time pollution monitoring of streams, lakes, ocean bays, drinking water reservoirs, local ponds, etc. For the undersea and offshore oil exploration, UWASN can perform oil leakage detection, equipment monitoring, and seismic imaging.

In addition, the relationship between the coherence time and transmission distances is also explored to reveal the fundamental difference between the short-range UAC and the medium-long range UAC.

Effective ICI Cancellation for OFDM Transmission in RA-UAC,otion and ocean waves lead to error-prone packet transmissions. To resolve the detrimental effect caused by the Doppler effect, we focus on the effective and low-complexity mirror-mapping-based OFDM transceiver design in this chapter.

Book 2016s the power allocation issues of two typical transmission scenarios, namely short-range transmission and medium-long range transmission. For the former scenario, an adaptive system is developed based on instantaneous channel state information. The primary focus is on cooperative dual-hop orthogonal
