Physical layer interface design and implementation for serial data transmission with multiplier technique approach

Serial communication enables communication between devices by providing high speed and efficiency in data transfer within modern communication systems. It has a wide range of applications, including business, healthcare, education, industry, and consumer electronics. This method offers an economical and efficient solution by requiring fewer cables and consuming fewer resources compared to parallel communication. It is particularly preferred in scenarios requiring remote communication and high-speed data transmission. Although serial communication offers speed and efficiency in data transfer, it also has certain disadvantages and limitations. In particular, the limited bandwidth for transferring large datasets and high-resolution media content can reduce its efficiency. This constraint poses a challenge for modern applications requiring higher speed and capacity. Despite its advantages, serial communication may necessitate more advanced technologies in certain cases. Numerous research and development studies have been conducted to address this need. Various techniques have been developed over time to enhance the speed and efficiency of data transmission. Line coding techniques have also evolved within this context. In this paper, a new technique (multiplier technique) has been developed with a new perspective on the line coding techniques used in serial data transmission by processing repetitive data to transmit multiple data units at once. This technique, like other line coding techniques, aims to increase the data transmission rate and overcome bandwidth limitations. In multi-level line coding techniques, instead of symbol data corresponding to each level, the coded data is derived by transmitting the number of repetitions of the logic value as a multiplier. In multi-level line coding techniques, instead of symbol data corresponding to each level, the encoded data is derived by transmitting the number of repetitions of the logic value as a multiplier. In the application example, within the logic voltage level range, a microcontroller, logic gates, and analog switches were used to analyze, deduplicate and replicate the data. In addition, an interface design and a basic-level protocol were developed for data transmission and analyzed for high data transmission efficiency based on various parameters included in the technique. In this study, interface and schematic designs were initially designed. Data was successfully transmitted to the receiver in a simulation environment using the developed basic protocol. The necessary printed circuit boards were fabricated to implement the hardware interface of the method. Data transmission was successfully achieved through hardware. Furthermore, the performance of the method was evaluated using various parameters. The results obtained indicate that the method can be used in many areas and may be considered among standard methods.
