Cost-Optimized SSB Transmitter with High Frequency Stability and Selectivity
نویسنده
چکیده
Single side band modulation is a widespread technique in communication with significant impact on communication technologies such as DSL modems and ATSC TV. Its widespread utilization is due to its bandwidth and power saving characteristics. In this paper, we present a new scheme for SSB signal generation which is cost efficient and enjoys superior characteristics in terms of frequency stability, selectivity, and robustness to noise. In the process, we develop novel Hilbert transform properties. Keywords—Crystal filter, frequency drift, frequency mixing, Hilbert transform, phasing, selectivity, single side band AM.

Recognition of Speech Enhanced by Blind Compensation for Artifacts of Single-Sideband Demodulation
This paper concerns the automatic recognition of speech that has been distorted by frequency shifting introduced by a transmitter-receiver frequency mismatch in communications systems using single-sideband (SSB) modulation. The degradation in recognition accuracy depends both on the frequency shift induced by mistuned SSB and additive noise, with a reduction in SNR causing the degradation produ...
متن کاملSpace-frequency turbo coded OFDM for future high data rate wideband radio systems
We propose a new bandwidth and power efficient signaling scheme for achieving high data rates over wideband radio channels exploiting bandwidth efficient OFDM modulation, multiple transmit and receive antennas and large frequency selectivity offered in typical low mobility indoor environments. Due to its maximum achievable transmit diversity gain and large coding gain, space-frequency turbo cod...
متن کاملInnovative demodulation method for SSB technique - Circuits, Devices and Systems, IEE Proceedings-
A single sideband (SSB) demodulation method is described, in which frequency mixing is not required. The proposed method is based on the phase shift method, but no local oscillator is employed. The IQ demodulator is replaced with an envelope detector and an FM demodulator. It can replace the synchronous demodulation method, whch requires an expensive phase-locked loop for carrier recovery. Not ...
