In this paper, based on analyzing the detector characteristics of modified Gardner (mGA) timing error detector examined before, an extended non-carrier-blind detector is proposed for quadratic phase shift keying (QPSK) signals. The timing jitter performance of new detector is about 2dB-10dB better than that of mGA at low and high signal-to-noise ratio (SNR) respectively. However, this advantage is...
We present a robust threshold setting strategy with modest computational complexity for frequency domain interference excision in direct sequence spread-spectrum (DSSS) communication systems. The proposed strategy calculates the threshold by multiplying the minimum value of the averaged squared magnitude with a predefined scaling factor. An analytical framework for choosing the scaling factor is developed...
