METHOD OF TRANSMITTING ADDITIONAL INFORMATION OVER UHF BROADCASTING CHANNEL

摘要

FIELD: radio engineering. SUBSTANCE: method uses odd harmonic of half of subcarrier of complex stereosignal in the capacity of subcarrier for signal of additional information. To decrease noises to main channel there can be used compensation signal on other odd harmonic of half of subcarrier of complex stereosignal. Compensation signal can also be used when receiving signal of additional information. EFFECT: enhanced reception range and authenticity of received information. 1 dwg
