A robust bandwidth digital channel (IBOC) audio streaming system to enhance the performance of existing FM broadcasting is being developed by Westinghouse for the US digital radio. UU. Both the analog FM signal and the DAB signal are transmitted simultaneously in the FM IB IB hybrid system. Broadcasters can simultaneously transmit analog and digital signals within the assigned channel mask, allowing full compatibility with existing analog receivers. It is shown here that the solution is tolerant to interference from adjacent channels, or interference from analogue co-channel transmission, even in an urban multi-signal multi-signal market. Although the main purpose of this document is to discuss compatibility issues between existing FM and DAB signals, the document also briefly describes spectral occupancy, power ratios, modulation formats and encoding, as well as frequency input And temporal diversity.
In-band on-channel (IBOC) is a hybrid method for transmitting digital radio signals and analog radio signals simultaneously on the same frequency. Using additional digital subcarriers or sidebands, the digital information is "multiplexed" into an AM or FM analog signal, thus avoiding reassignment of the broadcast bands. However, by putting RF energy out of the normally defined channel, interference to adjacent channel stations increases when digital sidebands are used.
IBOC allows multiple program channels, although this may involve taking some existing subcarriers out of the air to make additional bandwidth available in the modulation baseband. On FM, this could mean stereo deletion. In AM, IBOC is incompatible with analog stereo, and any additional channel is limited to highly compressed voice, such as traffic and weather. Eventually, stations can switch from hybrid mode (both analog and digital) to all-digital, eliminating monophonic baseband audio.
