Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem point that data included in noise causing trouble of communication can not be demodulated under an inferior condition. <P>SOLUTION: A burst signal is added at the head of data and used to demodulate the data, and secure high-speed communication under an inferior communication condition is enabled. A carrier signal (burst signal) is added at the head of the data to generate a basic carrier for the demodulation of the data, which is compared with a carrier to demodulate the data. To enable predictive demodulation of the carrier included in the noise which causes trouble of communication under the inferior condition, PSK modulation is performed at a zero-crossing point of the basic carrier when the data are modulated. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、劣悪な通信条件下での高速で確実な通信方式である。   The present invention is a fast and reliable communication system under poor communication conditions.

解消しようとする問題点は、劣悪な条件下での通信の障害となるノイズに含まれるデータ復調できない点である。   The problem to be solved is that data contained in noise that becomes an obstacle to communication under poor conditions cannot be demodulated.

信号の先頭部分に搬送波（バースト）信号を付け、送出側の搬送波との同期を取りノイズ精分に含まれる
信号を搬送波との比較により復調する、この復調をより正確に復調するため、送出側の変調方式を
ゼロクロスＰＳＫ変調とする。 Attach a carrier wave (burst) signal to the beginning of the signal, synchronize with the carrier wave on the sending side, and demodulate the signal contained in the noise precision by comparison with the carrier wave. Is a zero-cross PSK modulation.

デジタルでの無線通信、有線通信、光通信（赤外線）、超音波通信 等においてノイズによるデータの欠落を
最小 限度に止め高速で確実な通信が確保できるという利点がある。 In digital wireless communication, wired communication, optical communication (infrared), ultrasonic communication, etc., there is an advantage that data loss due to noise can be minimized to ensure high-speed and reliable communication.

バースト発信回路により送信側と同じ位相の内部搬送波発信し、  An internal carrier wave with the same phase as the transmission side is transmitted by the burst transmission circuit,

ピーク同期回路により信号受信時の周波数ずれを補正する、  Correct the frequency shift at the time of signal reception by the peak synchronization circuit.

内部搬送波とデジタル信号波との比較回路によりデジタル信号が復調する。 The digital signal is demodulated by a comparison circuit between the internal carrier wave and the digital signal wave.
