Tail-biting convolutional codes has been used in physical broadcast channel and physical downlink control channel of LTE, this paper introduces the architecture of the convolutional encoder and physical broadcast channel used in LTE, elaborating two common Viterbi algorithm, then a new CVA-based improved scheme is proposed, and in Physical broadcast channel system simulation is carried out. The conclusions...
A (240,K) Reed-Solomon decoding algorithm for CMMB (China Mobile Multimedia Broadcasting) application is presented. A modified Euclid's algorithm (MEA) Reed-Solomon decoding method was implemented for the Key Equation Solver. And an improved Forney algorithm is also proposed. The modified algorithm was analyzed and compared with BM algorithm. The simulation result shows that the modified algorithm...
