GIII-facsimile adapter for cellular mobile telephone using error control scheme

Abstract

An adaptive error control scheme suitable for mobile communication systems id described. An error-free high-speed data modem that uses an adaptive error control scheme is developed. Utilizing the error-free modem for which the error control scheme is adapted, a facsimile adapter which makes GIII-facsimile communication possible between a cellular mobile telephone and an office, and between two cellular mobile telephones, is developed. The error-free modem, a facsimile adapter as an example application of this modem, and modem LSIs which are developed for use in the signal converter unit of the error-free modem are described.<>
