PPT-A radix-8/4/2 FFT processor for OFDM systems

Jungmin Park Project b ackground OFDM used widely for highspeed digital communication High performance of FFT processor for real time application Dedicated FFT processor for only . Division Multiplexing CO-OFDM. 1. Principle of orthogonal frequency-division multiplexing (OFDM). The principles of orthogonal frequency division multiplexing (OFDM) modulation have been in existence for several decades. However, in recent years these techniques have quickly moved out of textbooks and research laboratories and into practice in modern communications systems. The techniques are employed in data delivery systems over the phone line, digital radio and television, and wireless networking systems. 1 1.1 and Receive 1.1.1 OFDM Downstream Transmit Fidelity Requirements 1.1.1.1 OFDM Channel Power and Bandwidth For the purposes of this specification, the number of occupied CEA channels of an OFD BELOW GROUND VEHICLE DETECTOR .
