CONSTITUTION: An address generator generates an address for reading data stored in an interleaver memory, being in B columns and F rows. Here, F is not equal to 2k (k is a positive number). The address generator includes a column counter(330), a row counter(350), a mapping device(360), and an adder(320). The column counter responds to B clock pulses, outputs 0 as the first column address, outputs a value obtain by adding an offset value F to previously outputted column address value (B-1) times, and generates a carry signal when the B clock pulses are completed. The row counter increases a count value one by one in response to the carry signal. The mapping device replaces the output of the row counter according to a predetermined row replacement rule. The adder generates the address using the output of the column counter as MSB and using the output of the mapping device as LSB.

Abstract: PURPOSE: An apparatus for performing a rate matching of a data communication system is provided to configure encoded symbols into rate matching blocks corresponding to an inverse number of an encoding rate, and to change values only of variables in a unified rate matching structure, so as to carry out rate matching processes for symbols encoded by a non-systematic code or symbols encoded by a systematic code. CONSTITUTION: A channel encoder(200) channel-encodes inputted information bits according to a code rate(R=k/n), and outputs encoded symbols. Rate matching units(231-239) separately receive the frame-unit encoded symbols as the number of same input symbols, which are decided according to a code rate. The rate matching units(231-239) perform puncturing/iterative processes for the received symbols. The rate matching units(231-239) puncture inputted symbols according to predetermined puncturing patterns to output the punctured symbols, or iterate the inputted symbols according to predetermined iterative patterns to output the iterated symbols. A MUX(Multiplexer)(240) multiplexes the rate matched symbols, and outputs the multiplexed symbols to a channel transmitter.

Abstract: PURPOSE: A device and method for normalizing state values of a structure decoder in a mobile communication system are provided so that state values accumulated in a current state can be normalized and outputted, when exceeding a predetermined reference value. CONSTITUTION: At least two structure decoders are connected in a serial chain structure, for performing a decoding operation according to an iterative decoding method, in an iterative decoder of a mobile communication system. A device for normalizing state values of the structure decoder detects state values of the respective states transited from a current state to a succeeding state. When the respective state values exceed a predetermined reference value, the device subtracts a predetermined value from the state values. Accordingly, the state values are normalized, and transited to the succeeding state. Here, an addition comparison selecting unit serves to normalize the state values. As a result, the device for normalizing the state values of the structure decoder can remove an error due to an overflow, and efficiently utilize a memory, by normalizing the accumulated state values for decoding.
