A device for the transmission of a plurality of data streams in the same volume and channel

摘要

PROBLEM TO BE SOLVED: To cope with contiguous channel interference in a contiguous area of an in-band on-channel system by transmitting multiple bit streams generated from an information signal according to multiple factors by using the frequency band of a host carrier signal.;SOLUTION: An embedded audio encoder 203 is supplied with an analog audio signal a(t) and generates a C stream, an El stream, and an E2 stream representing analog signals on leads 209a, 209b, and 209c, The bit rates of the C stream, E1 stream, and E2 stream are M, S1, and S2 kb/sec respectively. For example, when the encoder 203 is a 48 kb/sec audio encoder, M, S1, and S2 can be 16, 16, and 16, respectively. The quality of the combination of the C stream, E1 stream, and E2 stream is much higher than the analog AM quality.;COPYRIGHT: (C)2000,JPO
