Communication device and method of strong antiburst error

Abstract

A communication device capable of correcting a burst error exceeding a correcting capability of an error correcting code by only transmitting one packet. With respect to data to be transmitted, a frame generating section (22) generates a frame for which an error detecting process, etc., is performed. A frame dividing section (23) divides the generated frame, by a predetermined number, into a plurality of divided frames. A transmission control section (24) generates a packet in which the plurality of divided frame are copied predetermined times. A transmitting section (25) sends the packet to a receiver (4). A receiving section (35) receives the packet transmitted from a transmitter (4). A reception control section (34) divides the received packet by the predetermined number. A frame reconstructing section (33) reconstructs the frame by assembling the divided frames in predetermined order. A frame processing section (32) performs an error correcting process, etc., for the reconstructed frame.

Description

technical field [0001] The present invention relates to a communication device and a communication method with strong resistance to burst error (burst error), and more particularly to a communication device (transmitter, receiver, transceiver) that is not easily affected by burst errors caused by fading or interference and a communication method performed by the communication device, a program for executing the communication method, and a computer-readable recording medium recording the program. Background technique [0002] Now due to the progress of LSI, error correction technology is generally adopted even in the field of communication. As one of such error correction techniques, there is known a Golay code which is a block error correction code. For example, in Golay (24, 12), 12-bit data is transmitted with a 12-bit redundant code, and by doing so, up to 3-bit errors occurring in a total of 24 bits (1 set) can be corrected. That is, in an environment where errors occu...

AI Technical Summary

Problems solved by technology

In addition, in order to enable successful communication even if the duration of the burst error (noise) is increasing, multiple frame (packet) transmissions cannot be completed using the 3 times shown in the literature as an example

Therefore, the stop time must be increased more, so that the system overhead becomes very large, resulting in a decrease in transmission efficiency and an increase in delay time

Especially when used for machine control, since an increase in delay time is associated with a slow response, it is not practical for a system that is premised on sending multiple frames (packets)
