METHOD FOR THE RADIO COMMUNICATION OF DIGITAL DATA IN A NOISY ENVIRONMENT

摘要

The invention relates to a device for the radio transmission of a data word between a transmitter (1) and a receiver (65), comprising a transmitter (1) that can transmit at least one block of data comprising a preamble word and a data word repeated several times; an elementary synchronisation block allowing the synchronisation of the receiver (65) to the transmitter (1) and the detection of the preamble word; and a synchronous averaging device (67) calculating the average of the data word repeated.

1. A method of radio transmission of a data word between a transmitter and a receiver, comprising the steps of:
transmitting at least one data block comprising a preamble word known by the receiver and stored therein, followed by a data word identically repeated a plurality of times, the identical words being directly transmitted one after the other without transmitting any other word therebetween; detecting the preamble word; synchronizing the receiver to the transmitter, in phase and in frequency, during the reception of the preamble word; synchronously averaging the repeated data word; and detecting the transmitted data based on the synchronous averaging; wherein the synchronous averaging step comprises the steps of: receiving a data word repeated a plurality of times; storing each of the bits of the first received data word into a storage register; adding the value of each box of the storage register to each bit of the next data words; and dividing the value of each box of the register by the number of repetitions of the data word.
