Abstract
In wireless digital communications, amplitude-shift keying (ASK) and frequency-shift keying (FSK) modules are often used and radio frequency (RF), communication synchronization, and noise problems affect the performance very much. In particular, the sending of byte-type data called synchronous and preamble before sending data in intermodule communication increases the sent data and decreases the speed. Also, the microcontroller at the output of the RF receiver module continuously listens to the RF noise and analyzes incoming data, but this increases the processing load of the microcontroller. Moreover, it reduces the speed of performing other operations. In this study, a transparent RF transmitter and receiver have been investigated, and methods for increasing the communication performance of the modules have been proposed and performed. Two of the proposed methods prevented the continuous listening of the microprocessor in the RF receiver structure so that the microprocessor can be used with other processes. In other methods, the compression of the data size was achieved because the transmission of a series of data in RF communication systems was limited to a certain extent. In the last section of the study, since the RF modules have failed to transmit the data due to corruption in the extended data dimensions, the bit carrier control security code has been created for the data series and more healthy communication has been performed.
Highlights
It is well known in FRISS equations for wireless communication that the power received depends on the gain of the transmitter and the loss of the receiver [1]. e received signal strength in free space at a distance r from the transmitter is expressed in the logarithmic form as
Data compression was provided with the Differential Pulse-Code Modulation (DPCM) method for data transmission
It is shown that the data size can be increased because the data array to be discarded in a package in radio frequency (RF) modules is limited
Summary
It is well known in FRISS equations for wireless communication that the power received depends on the gain of the transmitter and the loss of the receiver [1]. e received signal strength in free space at a distance r from the transmitter is expressed in the logarithmic form as. It is well known in FRISS equations for wireless communication that the power received depends on the gain of the transmitter and the loss of the receiver [1]. According to FRISS equations, the power of the transmitter in wireless communication, the antenna gain of the transmitter, the antenna gain of the receiver, and the distance are the most important parameters that affect the communication [1, 2]. In short-range radio communication, RF power outputs several microwatts up to 100 milliwatts and the communication range is of several centimeters up to several hundred meters. It uses principally indoor operations and built-.
