We use theoretical models to compare the receiver signal to noise ratio (SNR) vs. average rate of detected signal photons for an integrated path differential absorption (IPDA) lidar using coherent detection with continuous wave (CW) lasers and direct detection with sine-wave and pulse modulations. The results show the coherent IPDA lidar has high receiver gain and narrow bandwidth to overcome t...
Design and Development of Ka Band Digital Beacon Receiver for Ka Band Propagation Studies Experiment
India is planning to conduct its own Ka band propagation studies experiment in order to validate the existing ITU model and to develop a more accurate prediction model for its unique climate condition for guaranteed QoS. This experiment involves measurement of signal attenuation due to rain and development of appropriate mathematical propagation models. This requires a ground receiver to receiv...
The description and performance analysis of a new OFDM/DQPSK signal receiver is considered in this paper. The proposed receiver has performance that is close to the performance for the coherent detection of the OFDM/DQPSK signal, in case of zero carrier frequency offset. In case of non-zero frequency offset, receiver with decision feedback differential detection (DFDD-OFDM) is often used in the...
A method, based on ideas from control theory, is described for the synchronization of discrete time trans-mitter/receiver dynamics. Conceptually, the methodology consists of constructing observer-receiver dynamics that exploit at each time instant the drive signal and past values of the drive signal. In this way, the method can be viewed as a dynamic reconstruction mechanism.
Recommended by Jörn Altmann This paper presents a simplified method for signal level clearance evaluation in each place of signal reception up to threshold for a given portable TV receiver device. It describes briefly the structure of transmission system considering the " 1Seg " structure of ISDB-T. The preliminary laboratory test was made before the field tests to verify the main features of h...
Previous work has demonstrated that a signal receiver based on a limiting form of the Shannon entropy is, in certain settings, more sensitive to subtle changes in scattering architecture than conventional energy-based signal receivers [M. S. Hughes et al., J. Acoust. Soc. Am. 121, 3542-3557 (2007)]. In this paper new results are presented demonstrating further improvements in sensitivity using ...
