in this paper, the effects of scintillation phenomena on bit error rate (ber) and signal to noise ratio (snr), which are essential characteristics in free space optical (fso) communication system, are studied. until now various methods have been introduced to decrease ber and increase the link's reliability. optimizing snr is one of the fundamental methods to decrease ber value. intensity fluct...

Today's telecommunications needs call for faster and more reliable networks. Optical transmission has allowed great advances in creating faster and more reliable global communications networks. Most optical networks are based on the SONET (North American) and SDH (International) standards. For my thesis, I have designed, implemented, and tested a bit-error rate monitoring circuit, compliant wit...

Preliminary -The BERTScope BSX-series Bit Error Rate Tester introduces a receiver test platform capable of supporting emerging Gen4 standards and beyond. With the addition of powerful data processing and internal Tx equalization, the BERTScope supports protocol-based handshaking and synchronization with your device under test (DUT), including interactive link training at data rates up to 32 Gb/...

Key performance specifications Up to 1.6 Gb/s Pattern Generator/Error detector for fast, accurate characterization of digital communications signaling systems PRBS or 8 Mb user-defined patterns provide the versatility to debug or verify any combination of digital signaling ANSI jitter measurements (RJ, DJ, and TJ) to measure the impact of random and deterministic jitter on the total jitter at B...
