How to reduce the bit error rate of OFDM
For this, numerous techniques are proposed to beat the PAPR problem like i) Selective mapping (SLM) ii) Partial transmit sequence (PTS), iii) Clipping, iv) Clipping and filtering. Current technological objectives for OFDM focus primarily on optimizing bit error rate (BER) performance, particularly in high-data-rate applications where transmission reliability directly impacts user experience. However, one amongst the foremost drawbacks of the OFDM system is that the high-peak-to-average power ratio (PAPR) that leads the system to provide in-band distortion and out-of-band radiation and reduces its efficiency. OFDM can be implemented easily, it is spectrally efficient and can provide high data rates with sufficient robustness to channel imperfections. Abstract-In this paper we present an analytical approach to evaluate the bit error rate (BER) of OFDM systems subject to carrier frequency offset (CFO) and channel estimation error in Rayleigh flat fading as well as in time and frequency selective fading channels.

Distributed temperature measurement fiber optic cable
Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. Advances in optoelectronics and associated signal processing have enabled the development of optical fibre distributed sensors with maximum ranges of several tens of kilometres. The unique feature of a distributed temperature sensing system is that it provides a continuous (or distributed) temperature. Distributed Temperature Sensing (DTS) is a fiber optic technology that enables real-time, continuous temperature monitoring over long distances, used widely in applications like pipeline leak detection, power cable monitoring, and transformer temperature management.

Relay Protection Vector Measurement
This paper studies vector surge estimation methods of four different commercial relays. Simulations of frequency and rate of change of frequency (ROCOF) variations, phase angle changes, islandings, short-circuits, and transmission events. The recently reported occurrences showed the spurious tripping of DG has been caused due to sensitive LoM settings, mainly by vector surge (VS, 78VS or vector jump) and ROCOF (81R) functions ,. 1547-2018 recommended ride-through requirements for which the LoM protection must ride-through during. The 78VS principle of operation is based on the phase displacement of voltage measured in the terminals of a synchronous generator operating in parallel with the grid when unintentional islanding occurs. When there is a sudden disconnection of the generator and the grid, the frequency accelerates (or decelerates) based on the power imbalance at the.
