Effects of Filters On The Performance of DVB-T Receiver
Digital Video Broadcasting-Terrestrial (DVB-T) is an international standard for digital television services. Orthogonal Frequency Division Multiplexing (OFDM) is the core of this technology. OFDM based systems like DVB-T can handle multipath fading and hence it can minimize Inter Symbol Interference...
Effects Of Filters on DVB-T Receiver Performance Under AWGN, RAYLEIGH and RICEAN Fading Channels
Digital Video Broadcasting–Terrestrial(DVB-T)has become a very popular technology for terrestrial digital television services.DVB-T is based on Orthogonal Frequency Division Multiplexing (OFDM)technique. OFDM is considered suitable for the DVB-T system because of its low inter-symbol Interference(...
