Interoperability and Performance Issues in Hf E-mail
نویسنده
چکیده
Electronic mail is particularly tolerant of the sometimes challenging HF radio communications medium. Its latency tolerance and store-and-forward delivery mechanism cope naturally with slow links and the occasional outage. This paper documents the results of a study of the interoperability and performance of leading standards applicable to e-mail service over HF networks, and recommends specific protocol suites for next-generation networks as well as directions for further research.

PD Controller Design with H¥ Performance for Linear Systems with Input Delay
This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...
متن کاملLow cost E-mail over HF with OFDM and turbo coding techniques
This paper presents a new low cost e-mail system for the HF band (3–30 MHz) based on free software and commodity hardware. The core of the system is a 2500 bps OFDM data modem enhanced by turbo codes and a powerful ARQ protocol. The modem has been deeply tested with a Watterson HF channel simulator [?, ], studying the impact of different configurable parameters and comparing its codification st...
