Abstract

A first communication device is provided. The first communication device modulates data to generate a first data symbol. The first communication device generates a first signal by using a first signal waveform allocated among a plurality of mutually orthogonal signal waveforms and the first data symbol. The first communication device outputs the first signal to a serial line connected to a second communication device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2014-0096777 filed with the Korean Intellectual Property Office on July 29, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a communication device and a communication method. Background technique [0004] A serial bus technology based on Inter-Integrated Circuit Communication (I2C) allows direct transmission and reception of data of logic signals (eg, '1' or '0') and supports a relatively low data transfer rate. [0005] Also, prior art data transmission and reception techniques require a process in which a master device selects a slave device. Prior art data transmission and reception techniques support communication between only one master device and one slave device at a time. Thereby, active communication between slave devices is impossible, and comm...
