چکیده
The double balanced mixer scheme in-phase signal input and double-quadrature Local Oscillator is suggested for application on IQ direct conversion receivers. LO leakage influence on DC component and BER of the digital signal is shown. A model of the system is designed which is illustrating the improvement of the receiver sensitivity in case of using the suggested scheme.

Improvement of Bit-Error-Rate in Optical Fiber Receivers
In this paper, a post processing scheme is suggested for improvement of Bit Error-Rate (BER) in optical fiber transmission receivers. The developed scheme has been tested on optical fiber systems operating with a non-return-to-zero (NRZ) format at transmission rates of up to 10Gbps. The transmission system considered is based on well known transmitters and receivers blocks operating at waveleng...
متن کاملBluetooth Low Energy Controller Low IF GFSK Modem
This paper presents the implementation of Bluetooth Low Energy Controller (BTLE), Low Intermediate Frequency (IF), Gaussian Frequency Shift Keying (GFSK) Modulation and Demodulation technique. The GFSK modulation uses a bandwidth bit period product BT=0.5. The modulation index shall be configurable between 0.45 and 0.55. A binary one shall be represented by a positive frequency deviation, and a...
متن کاملBER minimized OFDM systems with channel independent precoders
We consider the minimization of uncoded bit error rate (BER) for the orthogonal frequency division multiplexing (OFDM) system with an orthogonal precoder. We analyze the BER performance of precoded OFDM systems with zero forcing and minimum mean squared error (MMSE) receivers. In the case of MMSE receivers, we show that for quadrature phase shift keying (QPSK), there exists a class of optimal p...
متن کاملImprovement in Differential GPS Accuracy using Kalman Filter
Global Positioning System (GPS) is proven to be an accurate positioning sensor. However, there are several sources of errors such as ionosphere and troposphere effects, satellite time errors, errors of orbit data, receivers errors, and errors resulting from multi-path effect which reduce the accuracy of low-cost GPS receivers. These sources of errors also limit the use of single-frequency GPS r...
