位开销 (BO)、码率 (R)、前向纠错 (FEC)、错误检测、纠错、冗余位。摘要 在数据通信系统中，数据传输的可靠性和效率是重要的问题。采用前向纠错（FEC）技术的信道编码提高了数据传输的可靠性。前向纠错技术用于使用校验位（也称为冗余位）来检测和纠正数据中的错误。这些冗余位从数据中生成并与数据一起发送以检测和纠正数据中的错误。当具有冗余位的数据通过噪声信道传输时，噪声可能会破坏数据以及附加数据的冗余位。如果冗余位也被噪声破坏，则 FEC 无法检测和纠正数据中的错误。所提出的错误检测和纠正技术使用多向奇偶校验码来检测和纠正数据部分中的错误，并使用汉明码来检测和纠正多向奇偶校验位或冗余位中的错误。该技术是多向奇偶校验码和汉明码的结合，可以检测和纠正突发错误。利用MATLAB实现了汉明码多向奇偶校验码编码器和解码器的设计。

ABSTRACT In data communication system reliability and efficiency of data transmission are important issues. Reliability of data transmission is improved by channel coding which employs forward error correction (FEC) techniques. Forward error correction techniques are used to detect and correct the errors in data using check bits also known as redundant bits. These redundant bits are generated from the data and sent with data for detection and correction of error in data. When data with redundant bits is transmitted through noisy channel noise may corrupt data as well as redundant bits appended with data. If redundant bits are also corrupted by noise then FEC cannot detect and correct error in data. The proposed error detection and correction technique uses multidirectional parity code to detect and correct error in data part and Hamming code for detection and correction of error in multidirectional parity check bits or redundant bits. This technique is a combination of multidirectional parity code and Hamming code which can detect and correct burst error. The design of encoder and decoder for multidirectional parity code with Hamming code has been realized using MATLAB.
