Functional Description | Transmitter OperationFor the transmitter operation, communication waveforms are generated from the software tools running on the host computer at a low intermediate frequency (IF) of 12 KHz. SCK connects to USB port and appears as a Sound Card on Host computer. The generated waveform is sent to SCK in analog form via digital to analog converter (DAC) of SCK. SCK takes this IF signal and performs frequency up-conversion to the desired carrier frequency. This signal is further amplified, filtered and transmitted by the antenna. SCK is configurable from the host computer through USB interface and user can control transmission parameters like carrier frequency and output power level etc. from the host computer. ![]() Receiver OperationAt the receiver end another SCK receives the RF signal through its antenna and performs a series of receiver operations like channel filtering, low noise amplification and frequency down-conversion from RF to IF. This IF signal, which is available is sampled by the SCK's ADC and is provided as an input to the software application on the host computer through USB Interface. User can either develop his own Matlab/Simulink models or can use Renzym Software Framework (RSF) application for performing receive filtering, quadrature down-conversion and sampling rate reduction to produce complex baseband (in-phase and quadrature) signal. This baseband signal is further processed for receiver tasks like carrier and timing synchronization, equalization and error correction coding etc. Renzym SDR Framework (RSF) can be used to perform above mentioned receiver tasks for a wide range of modulation schemes. |

For the transmitter operation, communication waveforms are generated from the software tools running on the host computer at a low intermediate frequency (IF) of 12 KHz. SCK connects to USB port and appears as a Sound Card on Host computer. The generated waveform is sent to SCK in analog form via digital to analog converter (DAC) of SCK.

SCK is configurable from the host computer through USB interface and user can control transmission parameters like carrier frequency and output power level etc. from the host computer.

Receiver Operation
At the receiver end another SCK receives the RF signal through its antenna and performs a series of receiver operations like channel filtering, low noise amplification and frequency down-conversion from RF to IF. This IF signal, which is available is sampled by the SCK's ADC and is provided as an input to the software application on the host computer through USB Interface.

Overview | SDR communication kit (SCK) is a USB based plug and play device, designed for organizations and communication labs involved in the study, research and development of communication systems especially software defined radios. It can be used to readily build real-time communication systems by directly applying the concepts learnt from theory with a minimum of implementation effort in the hardware. One of its main advantages is that it provides direct interface, through USB port, with powerful simulation and analysis tools like Matlab/Simulink, Lab-View, GNU Radio etc. Computational and visualization capabilities offered by these tools can be used to design and analyze communication systems directly from simulations. This blending of theory and practice makes SCK an ideal candidate for analog/digital communication labs because this aspect is generally missing from most of the communication courses. Theoretical performance of various techniques can now be quickly compared with their performance in a real-world environment. Furthermore it provides a unique opportunity to the researchers working on receiver design to verify their algorithms in various practical scenarios. | |||||||||||||||
