A Novel Approach for Better Throughput in Near Field Communication Built by Ternary QAM using Tanner Tool

Abstract

This paper presents a high throughput analysis in Near Field Communication (NFC) using Ternary Quadrature Amplitude Modulation in 0.25µm CMOS process using tanner tool. NFC is a wireless communication works on the principal of electromagnetic induction that helps in the data transmission between active device and passive device. In the proposal there is a separate transmitter and receiver module for modulation and demodulation. The transmitter module consists of Ternary demultiplexer, 2:9decoder and Read Only Memory (ROM) for storing the ternary QAM modulated signal in the form of bits that is in phase and quadrature components. In the receiver side Mean Square Error (MSE) algorithm have used for detecting the bits accurately without any error. The receiver module consists of Full Subtractor, Multiplier, Adder and Divider. Ternary QAM appears to increase the efficiency of transmission for radio communication systems by using both amplitude and phase variations. In order to increase the levels and data rates, Ternary Quadrature Amplitude Modulation have used.
