Robust Frequency Hopping for High Data Rate Tactical Communications

摘要

An adaptive frequency hopping spread-spectrum (FHSS) modulation scheme is proposed which efficiently utilizes available transmission bandwidth, whilst providing robustness to jamming techniques in wireless tactical communication systems. The proposed technique operates by transmitting multiple, single-carrier, parallel transmission sub bands, which may occupy non- contiguous frequency regions. Simulation results demonstrate that the proposed scheme exhibits significant gain in error rate performance, as reduction in either the transmission data rate or an increase in transmitter power. In addition, the proposed scheme can adapt to use the available bandwidth for communicating, thus increasing the overall bandwidth utilization of the system.
