摘要： The present invention relates in general to a channel CODEC to increase the transmitting effect on a communication channel of a communication system, and more specifically to a branch metric module of a viterbi decoder. The module includes an operator for operating and outputting the differential magnitude of two signals, one signal being a code word generated to perform the viterbi decode and the other being a signal transmitted through the channel. An adder sums and outputs the data which is outputted to it from the operator. A receiving code word converter converts the magnitude of any of bits by the linear sampling quantization process, and non-linearly converts it in accordance with a preestimated or predetermined format. A number of operators calculate the magnitude between two signals at the absolute value to convert the magnitude of an inputted generative code word and the magnitude of the non-linear converted receiving code word. The adder sums and outputs the result to a branch metric converter, which converts the output according to the preestimated format.

摘要： A hybrid trace back apparatus and a high-speed Viterbi decoding system having the same are disclosed. The hybrid trace back apparatus includes: a register exchanging unit for receiving survivor values of each states from a path metric calculator, and obtaining a block survival value through a register exchange operation as much as a bit length for a block trace back operation; a first storing unit for the register exchange operation; a second storing unit for storing the block survival value obtained through the register exchange operation until the block survival value is written in a block trace back memory; and a block trace back unit for outputting decoded data by performing a block trace back operation while writing a value of the second storing unit.
