IPC: H04L27/22
Filed: 1995-06-01
Abstract: PURPOSE: To allow a receiver side only to discriminate transmission by a transmitter side without addition of a synchronizing signal by the transmitter side by sending all or part of individual multi-tones modulated by a required pattern at the transmitter side prior to transmission and discriminating the required pattern and demodulating the received tone signal by a measurement/ discriminating function of the receiver side provided to each individual demodulator for each tone. CONSTITUTION: A signal presence discrimination circuit 29 receives outputs from level measurement, devices 22, 23,..., 28 to measure the presence of tone signals. The signal presence discrimination circuit 29 uses any one of various methods such as a method that a total number of the presence of output levels of full band filters 11-18, for example, is obtained and total number of the presence of a reception level of each tone is obtained to discriminate it as a fact of transmission from the transmitter side when the number of presence of a reception level of each tone is within 1/8±α of the total number, or a method of majority decision that e.g. 5 tones or over in, 8 tones have a specified level or over.
