Systems and methods for advanced iterative decoding and channel estimation of concatenated coding systems

This invention describes methods for improving how digital radio signals, specifically HD Radio, are decoded and understood by a receiver. It uses advanced mathematical techniques to correct errors and estimate the quality of the radio channel, making the signal clearer. The claims focus on a specific process for HD Radio signals, involving initial signal breakdown, identifying known parts, and then using sophisticated filtering and combining methods to reconstruct the original information more accurately.
