This paper has deduced a precise SNR estimation algorithm for QPSK signals by using the methods of two-order statistics, data fitting, and considering the real and imaginary components of QPSK signal respectively. Comparing with the other two existing algorithms, this algorithm solves the problem of...
To date, no genome-wide characterization of the sucrose non-ferment 1 related protein kinase 2 (SnRK2) subfamily has been conducted in potato (Solanum tuberosumL.). In this study, eightStSnRK2 genes (StSnRK2.1-StSnRK2.8) were identified in the genome of the potato (Solanum tuberosumL.) ...
Space–Time Code Design for Correlated Ricean MIMO Channels at Finite SNR 来自 ResearchGate 喜欢 0 阅读量: 30 摘要: Space-time code (STC) designs commonly rely on the assumptions of independent and identically distributed (i.i.d.) Rayleigh channels (being either slow or fast fading) ...
A 100 MS/s 4 MHz Bandwidth 70 dB SNR ADC in 90 nm CMOS A 4th-order switched-capacitor $\\Delta\\Sigma$ ADC with a 4-bits quantizer is designed for a low-power direct-conversion receiver for Japanese ISDB-T and European DVB-T. It achieves a 76.3/70.1-dB SNDR over a 3.2/4-MHz...

考虑N支路的分集合并系统,每个支路是SNR=10dB的AWGN信道。假设采用M=4的MQAM调制,误码率近似为Pb=0.2e-1.5γ/(M-1),其中γ是接收信噪比。(
