Abstract: This paper presents performance comparison of various modulation techniques in almouti scheme with Rayleigh fading channel. In the comparison, the space time coding has been used. The performance comparison are made on the basis of symbol error rate(SER) performance matrices over Rayleigh fading channel with 16-PSK,QPSK,PAM,16-QAM,64-QAM modulation technique. The comparison results show that in Rayleigh fading the symbol error rate is least for QPSK modulation technique as compared to other three modulation techniques i.e. M- QAM ,PAM and 16-PSK.

Author(s): B.K. SINGH , SAPNA
Abstract: Sub-threshold operation holds promise for ultra low energy operation in emerging applications. Sub-threshold operation is attractive for mid to high performance applications where power has become a limiting constraint. This paper proposes a low power Schmitt-Trigger using CMOS standard cell logic. Experimental results reveal that proposed design has reduced power consumption and has temperature sustainability. The paper also presents the application of Schmitt Trigger in SRAM. The simulation work has been done on Tanner EDA tool at 45nm technology.
