摘要： Improved error screening techniques for use in processing digital audio or other types of information received in a digital communication system. Control information associated with a given packet of the received information is identified and compared with a decoding requirement of the packet, in order to control the generation of an error indicator for the packet. More particularly, the error indicator may be generated in response to an inconsistency between the control information and the decoding requirement. For example, the control information may include an indication of packet length that can be compared to a number of bits required to decode the corresponding packet, with any inconsistency between the packet length indication and the number of required bits leading to the generation of an error flag for the packet. The invention is particularly well-suited for use in the processing of encoded digital audio information received in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system, but is also applicable to other types of information and other types of communication systems.

摘要： Techniques for processing received information in a communication system, such that performance is significantly improved in the presence of certain types of interference. In an illustrative embodiment, first and second digital sidebands are transmitted on either side of an FM or AM host carrier signal in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The compressed digital audio information in the sidebands is encoded using an outer code, e.g., a cyclic redundancy code (CRC), and an inner code, e.g., a complementary punctured pair convolutional (CPPC) code. A receiver generates an error indicator based at least in part on a first decoding of the received information. The error indicator characterizes interference associated with at least one of the digital sidebands. The receiver then generates at least one alternative decoding of the received information if the error indicator has a designated characteristic. For example, the receiver may generate the alternative decoding by eliminating from consideration in the receiver decoding process a designated portion of at least one of the digital sidebands. The error indicator may be indicative of the presence or absence of a first adjacent interference signal of a particular level within a frequency band associated with one of the sidebands, and may be based on, e.g., a signal-to-noise ratio measurement generated from a pilot tone associated with a given sideband, and/or an error flag generated using the CRC outer code Portions of the given sideband may be eliminated from consideration via successive erasures of sideband components, i.e., subbands, thereby resulting in an increase in the effective code rate of the inner code.
