A fully digital noncoherent and coherent GMSK receiver architecture with joint symbol timing error and frequency offset estimation
2000
IEEE Transactions on Vehicular Technology
Preserved Fulltext
We propose a fully digital noncoherent and coherent Gaussian minimum shift keying (GMSK) receiver architecture with joint frequency offset compensation and symbol timing recovery in this paper. ...
The bit error rate (BER) performance of this GMSK receiver architecture is assessed for an additive white Gaussian noise (AWGN) channel by computer simulation. ...
In this paper, both noncoherent and coherent demodulation of a GMSK signal under a unified receiver structure are investigated. ...

Based on this model, a noncoherent demodulation method of CPM signals, that uses an Extended Kalman Filter (EKF), was developed. ...
The performances of the demodulation method were tested on two types of CPM modulated signals, embedded in noise: Minimum Shift Keying (MSK) and Gaussian Minimum Shift Keying (GMSK). ...
In this paper, we propose a noncoherent procedure that uses Extended Kalman Filtering (EKF) to demodulate the MSK and GMSK signals. This paper is structured as follows. ...

A noncoherent Gaussian minimum phase-shift keying (GMSK) detector using differential phase detection combined with the soft-output Viterbi algorithm (SOVA) is presented. ...

However, the proposed JVDD scheme uses only one Viterbi processor by modifying the branch metric with inter-symbol interference information from GMSK modulation; therefore, the hardware complexity can ...
Since the convolutional coded Gaussian minimum-shift keying (GMSK) signal is specified in the BLE 5.0 standard, two Viterbi processors are needed for detection and decoding. ...
In addition, the use of the convolutional code helps improve the receiver sensitivity, thereby dramatically increasing the coverage performance. ...
