“…Each frequency division consists of 18 data subcarriers and one reference subcarrier, with a subcarrier spacing of 363.4 Hz. Table 1 describes the most important parameters of the IBOC FM system [3]. Tables 2 and 3 depict the characterization of the primary and secondary logical channels, respectively, according to the established service mode for transmission.…”

“…These challenges include finding adequate coexistence between analog and digital radio within the bandwidth established for each AM or FM radio channel, reducing interference levels during analog signal reception, and evaluating appropriate power levels for the transmission of the two types of signals, among other aspects [2]. Additionally, an optimal digital radio system must offer efficiency and spectral flexibility, with the ability to provide high transmission speed rates without monopolizing continuous bandwidth within a dynamic broadcasting context [3].…”

The hybrid in-band on-channel (IBOC) transmission system, which serves as a digital audio radio scheme, facilitates the simultaneous transmission of analog FM and digital audio. In IBOC systems, broadcasters transmit signals within allocated channel bands, posing a challenge in bandwidth allocation for digital audio transmission. To address this, cooperative game theory, supported by the bankruptcy game and Shapley’s value, is proposed as a strategy to optimize bandwidth allocation at each node or station. This approach considers service demand, the number of stations, and radio channel conditions in the FM band. The paper presents a scenario under saturated traffic conditions to evaluate the degree of optimization achievable using the Shapley value under clearly defined traffic and channel conditions. The results indicate that cooperative game theory, with the support of the Shapley value, offers an excellent alternative for optimizing bandwidth in digital broadcasting over IBOC in FM, with potential applicability in other digital radio broadcasting systems.
