Opis

Recently, a worldwide convergence has occurred for the use of Orthogonal Frequency Division Multiplexing (OFDM) as an emerging technology for high data rates. In particular, many wireless standards (Wi-Max, IEEE802.11a, LTE, DVB) have adopted the OFDM technology as a mean to increase dramatically future wireless communications. It is proposed that the multi beam forming smart antenna systems using OFDM technique can offer variable bandwidth, improved protection for angle of arrival in calculated amount of phase difference. In this paper, we introduced a DVB-T2 based multi beam forming for smart antenna system. DVB-T2 is a OFDM standard. For that we are using two techniques namely SMI & FFT .While using the SMI technique for beam forming the more computational time is required with maximum no. of complex multiplier is used. to reduce this the FFT algorithm is proposed here to increase the throughput & accomplish digital beam forming & AOA. The proposed system is focus on the design of digital beam forming wideband communications waveforms using FPGAs.
