But OFDM is very sensitive to frequency offset and phase noise, so synchronization is the key problem for OFDM system.
但是OFDM技术对频率偏移和相位噪声很敏感,所以同步是OFDM系统中的关键问题。

It is proved that UV channel is a minimum phasesystem and can use blind equalizer. Ber is not sensitive to the step size and tap number for CMA blind equalizer.
This system combines a highly insulated cooler with a liquid nitrogen reservoir so to maintain temperature sensitive samples at vapor phase temperatures.
