To allow for coherent demodulation at the user equipment, reference symbols (or pilot symbols) are inserted in the OFDM time-frequency grid to allow for channel estimation. Downlink reference symbols ...

If you want to extract a signal from a huge amount of noise, a lock-in amplifier is the ideal tool. But when it comes to buying one, doing your homework first can avoid a costly mistake, advises ...

Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...

“Our partnership with Idea! delivers a software-based ISDB-T solution for customers that enables significant cost efficiencies and shortens design cycles for DTV demodulation,” said Eran Briman, vice ...
