摘要
Demodulation and decoding for frequency modulation (FM) receivers with radio data system (RDS) or radio broadcast data system (RBDS). An example of a method for processing a signal in a receiver includes quantizing a demodulated signal to generate bits in response to receipt of the demodulated signal. The method also includes grouping the bits into one or more blocks. The method further includes computing a syndrome for a block from the one or more blocks. Moreover, the method includes identifying error, corresponding to the syndrome, in the block based on type of demodulation. The type of demodulation includes a coherent demodulation and a differential demodulation. Furthermore, the method includes correcting the error in the block.
