Various PSK modulation schemes for wireless communication

In this paper, various PSK Modulation schemes for wireless communication systems are designed and simulated using MIC techniques are presented. Three modulation schemes namely, Bipolar phase Keying (BPSK), Quadrature phase shift keying (QPSK), Eight-Phase-Shift Keying modulators (8-PSK) are designed at the S-band (2.4 GHz) that allows to achieve a very high accuracy in phase with very low power consumption. The configuration of the proposed PSK modulator is of parallel type, simulated using microstrip. The isolation between the carrier input port and the output port is very high and the phase error is the less than 2⁰. The substrate used for the PSK modulator is FR4 and the specification for substrate is dielectric thickness (h)=0.8mm, conductor thickness(t) = 0.035mm, dielectric constant(€)=4.4 and tangent loss=0.001.
