    • The invention relates to an error correction method used in the transmission (15) of a date (D) via a communication system (1). According to said method, at least two data words (DWA, DWB) consisting of two bits are generated for the date (D) according to a predetermined coding rule (7). One of the generated data words (DWA, DWB) is selected taking into consideration (11) a running digital sum produced using the corresponding data word and the running digital sum of the selected data word (DW) is used to produce (9) a first running digital sum (S1). The selected data word (DW) is converted to a code data word (CDW) according to a modulation method (13), whereby one bit of the data word (DW) each is associated with a two-bit sequence having two different individual bit values. The code data word (CDW) and the first running digital sum (S1) are transmitted. The received code data word (CDW') is inspected for the presence of a two-bit sequence having two identical individual bit values, thereby making it possible to identify defective two-bit sequences and to correct the error using the first running digital sum (S1).

    • PURPOSE: An encoder for converting serial data to parallel data, a decoder for converting serial data to parallel data, and a data transfer device for transferring serial data are provided to reduce effectively RF elements of transmitting data and restrain EMI(Electro-Magnetic Interference) by reducing changing points of serial data. CONSTITUTION: An encoder includes a changing-point counter, a code converter, and a parallel/serial converter. The changing-point counter(1) counts change of n-bit data at each changing point and generates a counting result. The changing-point counter outputs a discrimination bit of a true value when the counting result is over a predetermined value. The code converter(3) converts the n-bit data in such a way that bits of the n-bit data located at predetermined positions are inverted when the discrimination bit is true. The parallel-to-serial converter(5) converts (n+1)-bit data to a (n+1)-bit serial code.

    • A communication system and a control method thereof are provided to decrease an SSN(Simultaneous Switching Noise) and an ISI(Inter Symbol Interference) noise by partially inverting data to be transmitted before transmission. A communication system includes a transmitter(2100) and a receiver(2200). The transmitter inverts first bits of first transmission data(DATA) based on an error signal, and serializes the first transmission data to generate second transmission data(DOUT0-DOUT3). The transmitter transmits the second transmission data to plural communication channels(CH1-CH4). The receiver inverts the first bits of first reception data(DIN0-DIN3) which is received from the communication channels based on an error signal, and inverts the received first bits. The receiver parallelizes the first reception data to generate second reception data(DI). The receiver generates the error signal based on the second reception data.
    • 提供一种通信系统及其控制方法,通过部分地反转在传输之前传输的数据来减少SSN(同时切换噪声)和ISI(符号间干扰)噪声。 通信系统包括发射机(2100)和接收机(2200)。 发送器基于误差信号反转第一传输数据(DATA)的第一位,并串行化第一传输数据以产生第二传输数据(DOUT0-DOUT3)。 发射机将第二传输数据发送到多个通信信道(CH1-CH4)。 接收机根据误差信号反转从通信信道接收到的第一接收数据(DIN0-DIN3)的第一比特,并且反转所接收的第一比特。 接收机将第一接收数据并行化以产生第二接收数据(DI)。 接收机根据第二接收数据产生误差信号。
