Title:
DUAL CARRIER MODULATION-BASED DATA TRANSMISSION METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/041690
Kind Code:
A1
Abstract:
Provided in embodiments of the present invention are a dual carrier modulation (DCM)-based data transmission method, device and system. When a binary convolutional coding is adopted and a transmission bit rate is greater than 1/2, the embodiment of the present invention utilizes different puncture patterns, that is, a first puncture pattern and a second puncture pattern, to puncture first data obtained by the binary convolutional coding. Although the first puncture pattern and the second puncture pattern are used to puncture different bits for two identical data, the obtained punctured data, first punctured data and second punctured data, have the same transmission bit rate, and thus a receiving end can obtain the punctured bits of one data from the other data and thereby obtain a coding gain. Also, in contrast to the existing DCM technique, the present invention can reduce a bit error rate of DCM-based data transmission and increase the reliability of data transmission.
