This paper presents a method to grade answer papers written by the students by assessing the semantic similarity between the written answers and the actual answers and grading them accordingly based on the amount of semantic similarity between the two.
In this study of OFDM transreceivers, with the help of GNU Radio Companion and SDR, we have made an attempt to create a simulation environment similar to real-time channel conditions, by considering the parameters such as bit error rate, channel fading losses, and Doppler spread, and analysed the performance of OFDM transreceiver system.
