Differential detection of GMSK signals with low BtT using the SOVA
نویسنده
چکیده
A noncoherent Gaussian minimum phase-shift keying (GMSK) detector using differential phase detection combined with the soft-output Viterbi algorithm (SOVA) is presented. This approach overcomes the severe intersymbol interference (ISI) of GMSK signals with low BtT . Unlike conventional detectors the SOVA produces soft-decision bits resulting in larger coding gains in subsequent convolutional decoders.

Sequence Estimation Scheme of Narrowband Digital FM Signals using Limiter-Discriminator Detection with SOVA
The sequence estimation scheme of narrowband-IFfiltered digital FM signals like GMSK and CPFSK with noncoherent Limiter Discriminator detection with Integrate & Dump filter has been reported previously by the same author. In this paper we have applied Soft Output Viterbi Algorithm (SOVA) to the sequence estimation scheme to further utilize the Log Likelihood Ratio (LLR) of the decoded bit. Usin...
متن کاملTurbo Equalization of Gmsk Signals Using Limiter-discriminator
Sequence estimation (SE) of narrow-band digital FM signals, such as GMSK or CPFSK, with noncoherent limiter/ discriminator (L/D) and post-lowpass filter detection, was investigated in [1]-[3]. This paper proposes a novel Turbo equalization scheme of GMSK signals, where the iterative decoding between the inner ISI decoder and the outer Recursive Systematic Convolutional (RSC) decoder has been do...
متن کاملtransformer differential protection using the fault-generated high-frequency transient components
Power transformers are the most important components of a power system, so their protection is a critical issue. This paper proposes a novel and efficient algorithm based on the high-frequency components of the differential current signal to discriminate between the magnetizing inrush currents and the internal faults. After detecting the over-current in the differential current signals, samples...

This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...
متن کامل15.2 Threshold Detection Performance of GMSK Signal with BT=0.5
This paper considers the detection performance of a serial thresholding receiver for preceded bina~ GMSK signal with BT=O. 5. The conditional symbol (biij error probability of the GMSK signal with carrier phase and timing errors is derived and compared to that of unfiltered BPSK. It is shown that the GMSK signal has practically the same performance as the ideal BPSK signal in the absence of syn...
