The main objective of this paper is to show the design implementation of an OFDM (Orthogonal Frequency Division Multiplexing) transmitter that will be part of a future DVB-T demonstrator. After system modeling and simulation, we proceeded with the design architecture synthesis which will be mapped to the Virtex-II Pro™ devices. Thanks to the flexibility of the proposed architecture, the transmitter...
