A study of wireless video communication system using PHS

In Japan, with the start of the Personal Handy Phone System (PHS)(1) service in 1995, there has been increased activity aimed at developing on mobile-multimedia communication services that take advantage of the system's high 32-kbps speed. Since wireless transmission paths suffer from fading errors, an important task in the implementation of mobile-multimedia communication services will be to guarantee high-efficiency communication despite the error-laden transmission channel. We present a study of a highly error-tolerant re-transmission-control method.
