Due to multipath component signals generated by reflection and other interference during signal transmission, the receiving end utilizes multiple antennas to simultaneously receive signals from different paths, and then selects and combines these signals into a total signal to reduce the impact of signal fading. This i...
With the development of DVB-T in outdoor broadcasting fields such as mobile TV, car TV, building TV, subway TV, etc., small range fading such as multipath fading and Doppler frequency shift is inevitable in these reception ranges. Solving these fading and interference has become a highly concerned issue. In order to ad...
Everyone is familiar with television antennas. I remember that the old-fashioned black and white TV used to come with its own antenna and later developed into outdoor pole TV antennas. But so far, television antenna technology has further matured, and the current antennas can greatly meet our daily needs. However, many...
