Abstract :
A novel architecture of the precoding is proposed for pre-distortion based transmitters. To reduce the circuit complexity, we introduce a parallel prefix network based a DQPSK precoder, a flip-flop based look up table, and a coordinate transformation for a dual drive Mach-Zehnder modulator.
