RADIO DATA TRANSMITTER/RECEIVER

PURPOSE:To discriminate the end of received data without using a stop bit by providing a means which eliminates unrequired data due to a noise on the rear terminal part of the data in a data fetch means. CONSTITUTION:The reception means 21 of reception side equipment 2-4 receive radio data from transmission side equipment 1, and output a reception signal including the radio data and a carrier sense signal. Thence, the elimination means 22a of the data fetch means 22 eliminates the unrequired data on the rear terminal part of the received data equivalent to the delay component of the carrier sense signal by prescribed reference. After that, the means 22 fetches a reception data signal from a reception signal based on the carrier sense signal from the means 21. Therefore, the unrequired data due to the noise on the rear terminal part of the received data can be prevented from being received. Also, the end of the received data can be discriminated without using the stop bit, which improves transmission efficiency.
