Opis

The aim of the book is to design, simulation and implementation of the Discrete Multitone (DMT) modulation for ADSL based on Software Defined Radio (SDR) using FPGA. DMT divides the available bandwidth into parallel sub-channels. The main units of the DMT modulator are serial to parallel converter, symbol mapping, IFFT, parallel to serial and cyclic prefix. There are two techniques to transmit data namely complex transmission and real transmission .Real transmission is preferred for DSL, since it needs single wire but uses twice number of IFFT.
