  Stretchable Antennas for Next Generation Communication Systems

  By Amita Agnihotri, Uma Sharma, Deeksha Sharma

  Abstract: Due of its extensive applications in fields such as biomedical applications and wearable devices, the internet of things, and 5G applications, demand for flexible wireless communication systems is expanding. Flexible wireless communication necessitates stretchable antennas. Flexible electronic devices has many advantages like easy portability, light in weight and use of ecofriendly materials. The popularity of flexible electronic devices is due to these properties. The selection of flexible or stretchable antenna …

  Massive MIMO Technologies: A Review

  By Amita Agnihotri

  Abstract: This paper discusses the study and exploration of massive Multiple-Input Multiple-Output (MMIMO) wireless access technology spurred by the global bandwidth shortage in the wireless communication sector (MIMO). Massive MIMO is a major enabling technology for next-generation networks that combines antennas at both the transmitter and receiver to enable exceptional spectrum and energy efficiency with little processing. The effective deployment of 5G—and beyond—networks to realise diverse applications of the intelligent sensing …

  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 …
