Method and apparatus for transmission and reception of in-band on-channel radio signals including complementary low density parity check coding

A method includes: constructing complementary low density parity check codewords by generating a first codeword having a first code rate; and partitioning the first codeword by assigning groups of bits of the first codeword to four quarter-partitions, wherein each of the quarter partitions includes bits in one half of one of four independently decodable semi-codewords each having a second code rate that is larger than the first code rate. Receivers that receive signals produced by the method are also disclosed.. ... Ibiquity Digital Corporation

First adjacent canceller (fac) with improved blending using a parametric filter

A method for processing a radio signal includes: receiving an fm in-band on-channel radio signal including a plurality of digitally modulated subcarriers in upper and lower sidebands; sampling the fm in-band on-channel radio signal to produce an input signal including complex digital samples of a combination of a desired one the upper and lower sidebands and an fm interferer; removing fm interferer components from the first signal by notch filtering to produce a notch-filtered signal; weighting the notch-filtered signal to produce a weighted notch-filtered signal; using a parametric filter to filter the input signal to produce a parametric-filtered input signal; and combining the weighted notch-filtered signal and the parametric-filtered input signal to produce an output signal. A radio receiver that implements the method is also included.. ... Ibiquity Digital Corporation
