  OFDM Systems with Reduced PAPR

  By Amita Agnihotri, Dhairya singh, Ashish Kumar Jha

  Abstract: To reduce peak to average power radio (PAPR) of orthogonal frequency division multiplexing (OFDM) system, flexible and distortion less methods like SLM (Selected mapping) and PTS (Partial transmit sequences) are very useful. The variation of OFDM signal amplitudes is very wide with high PAPR. Huge PAPR necessitates a DAC with sufficient dynamic range to handle the OFDM signals' large peaks. PAPR reduction has been demonstrated to save considerable amounts of …

  Ingenious Parking System based on IoT

  By Amita Agnihotri, Ankur khera, Ashish Kumar Jha, Ayush Bhatnagar, Dhairya Singh Tomar

  Abstract: The internet of Things (IoT) is in a position to attach billions of devices and services at any time in anywhere, with various applications. Recently, the IoT became an emerging technology. A metropolitan city has over a million of cars on its roads but it does not have enough parking space or it is difficult to seek out a parking lot. However, this paper proposes a modern solution to such …
