Implementation of Digital Up Converter and Down Converter using System Generator

Due to the increasing complexity in modern communication systems, data communication systems make extensive use of digital hardware. Modern data communication systems utilize a lot of digital hardware because of the complexity of modern communication systems, which is expanding. The frequency tuning function is converted from analog to digital and implementation in addition to baseband digital processing, with integration, cost, and programming case as the main drivers. The objectives are producing a cost-efficient hardware implementation that is optimized. An FPGA-based implementation platform is necessary due to the many hardware requirements for these systems, including processing speed, flexibility, integration, and time taken to market. According to the characteristics of each communication system, they have different purposes, using different modulation methods, different encoding methods, and hardware-based communications systems and traditional systems cannot meet people's needs. In this project, the most essential components of a digital radio system, including a Digital Up and Down Converter for Remote Radio Head for Long Term Evolution. A DUC performs the task of filtering and up-converting the baseband signal to a higher sample rate as part of the transmit route of the digital radio front end signal processing system. A DDC is a component of the reception path of a digital radio frontend signal processing system. By decimating to a lower sampling rate, it enables the extraction of information of interest. The most recent technology used in distributed architecture is the remote radio head. Each block of the DUC and DDC is done using a MATLAB tool. Current data communication systems utilise a lot of digital hardware because of the complexity of modern communication systems, which is expanding. This frequency tuning function will be converted from analogue to digital implementation in addition to baseband digital processing, with integration, cost, and programming case as the main drivers. In this project, a suggested method for using digital up converters and down converters is described. This method avoids the issue of bit growth in the cascaded integrator comb filter, which raises the bit error rate and lowers system performance owing to the development of words due to indeterminate data. The overall construction of a digital IF receiver is examined using a system generating platform, a digital controlled oscillator, and a decimation filter model in MATLAB/Simulink.
