More Information
Summary:The invention relates to a method for FEC (Forward Error Correction) decoding of a frame structure supporting dynamic FEC parameters, and a receiver, comprising: a demodulator that demodulates an input signal stream thereby generating a demodulated input signal stream; an FEC (Forward Error Correction) decoding functional block that performs FEC decoding of the demodulated input signal stream using a first plurality of FEC decoding parameters; €ƒ€ƒ€ƒ wherein the FEC decoding functional block detects a CP (Control Packet) within the demodulated input signal stream; €ƒ€ƒ€ƒ a parameter extraction functional block that acquires a second plurality of FEC decoding parameters from the CP and the second plurality of FEC decoding parameters is fed back to the FEC decoding functional block; and €ƒ€ƒ€ƒ wherein the second plurality of FEC decoding parameters correspond to a plurality of FEC blocks that is a predetermined number of FEC blocks apart from CP within the demodulated input signal stream.
