Description: This Recommendation defines the procedures used by Group 3 facsimile terminals as defined in ITU-T Rec. T.4. These procedures enable documents to be transmitted on the general switched telephone network, international leased circuits and the Integrated Services Digital Network (ISDN). Further, these procedures allow communication to be manual or automatic and for document transmission to be requested alternatively with telephone conversation.With this revision, the colour spaces defined in ITU-T Rec.

Description: Rayleigh fading channel, Rayleigh fading channel) is a statistical model of radio signal propagation environment. This model assumes that the signal through a wireless channel, its signal amplitude is random, show the "decline" features, and multipath fading signal envelope obeys Rayleigh distribution. As a result, the multipath fading is also called Rayleigh fading. The channel model can be described by the ionosphere and troposphere reflect shortwave channel, as well as a built-up urban environment. Rayleigh fading is only applicable to direct signal from the transmitter to the receiver does not exist, or rice fading channels as channel models should be used.

Description: Features: Fax demonstration program
The specific operation process is as follows:
1) set the hair (closing) Fax file (can be set to start sending and receiving files from the specified page). (Received fax needs to set the store file path)
2) play tone dialing, off-hook, and select the send and receive fax operation.
3) to begin accepting (hair) Fax.
4) the end of the operation, hang up.
For an extra note file you need in the fax has begun coupled issuing documents. And, additional file format should be the same in the hair file format. Issued a document such as a Fax file, you can only add hair Fax file issued a document, can only be made Tif file Tif file.
