Investigation on In-band Interference Effect and Out-of-band Interference Mechanism of B1I Navigation Receiver

A Software-Defined Radio Receiver in 65nm CMOS Robust to Out-of-Band Interference

Two techniques are presented in this paper for a software-defined radio (SDR) receiver robust to out-of-band interference. Voltage gain is realized at IF simultaneously with low-pass filtering to mitigate blockers and out-of-band intermodulation distortion. A 2-stage polyphase harmonic rejection (HR) mixer concept robust to gain error achieves 2-6 HR of more than 60dB for 40 samples without tri...

Effect of Partial-Band Interference on Receiver Estimation of C/N0: Theory

John W. Betz is a Consulting Engineer at The MITRE Corporation. He received a Ph.D. in Electrical and Computer Engineering from Northeastern University. His work involves development and analysis of signal processing for communications, navigation, radar, and other applications. He developed the Binary Offset Carrier modulation for the GPS M code signal, and more recently has been contributing ...

Real-Time Interference Detection in Tracking Loop of GPS Receiver

Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...

Dealing With AM Broadcast Band Interference to Your Receiver

an investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
