Bit Error Rate (BER) is a measure of telecommunication signal integrity based on the quantity or percentage of transmitted bits that are received incorrectly.

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.

faults in communication optical cables can stem from various factors, including physical damage, bend radius violations, water ingress, connector and splice issues, fiber aging, extreme temperatures, rodent damage, manufacturing defects, environmental conditions, installation. Identifying and understanding the causes of these faults is crucial for ensuring reliable and efficient communication networks. Fiber optic cables are the backbone of modern communications, delivering high-speed data over long distances with minimal loss. When issues like signal loss, slow speeds, or intermittent connectivity arise, systematic troubleshooting is key. Optical cables in laying and use often encounter some problems, this paper summarizes 7 common optical cable failures, easy to check in the inspection, and quickly finds the cause of the failure.
