| Abstract | In-Band On-Channe (IBOC) digital audio broadcasting (DAB) is a method of digital audio radio , which could transmit analog FM and digital audio simultaneously. However, due to the existence of fading and interference in FM bands, transmit capacity has reached its limitations for the bandwidth, thus, adding digital transmission in the crowded FM band is a challenging proposition. Diversity is one of the key techniques for digital transmission. Space-time block code (STBC), the technique of temporal diversity, is applied to raise transmission reliability. Meanwhile, bit-interleaved coded modulation (BICM) can provide spatial diversity without occupying high bandwidth. Based on spatial and temporal diversity, a scheme that STBC is embedded into MIMO-BICM, can add the reliability and effectivity of transmission over fading channels. In this paper, a type of coded modulation scheme was proposed in Hybrid in-band on-channel system, by use of BICM-STBC instead of the convolutional code, and would get coding gains without bandwidth expansion. The simulation results show that the proposed scheme can effectively improve the receiving performance of an FM IBOC system over Rayleigh fading channels, with about 2dB coding gains when BER is below $10^{−5}.$ |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
