TRED HF Communication System Analysis
Abstract
A design technique based on obtaining equality of quasi-minimum atmospheric noise and receiver internal noise at the receiving subsystem input is established and applied to three representative system arrangements. Special attention is given to the characteristics needed to protect the (S + N)/N ratio at the receiver output from excessive degradation due to interference from transmitters operating on the same ship while maintaining maximum usable receiver sensitivity. An unexpected conclusion is that requirements for interference-free operation are harder to meet at the high-frequency end of the band.
