Noise Figure Measurement of Highly Mismatched DUT
(Společnost pro radioelektronické inženýrství, 2003-09)A device mismatch seriously degrades the accuracy of its noise figure characterization. A new second stage correction technique for highly mismatched device under test is proposed and compared to the standard technique. ... -
On the UMTS Downlink Capacity in (Open Rural and Countryside) Zone Near Deep Space Network (DSN) Installations
(Společnost pro radioelektronické inženýrství, 2003-09)The UMTS macrocell downlink capacity is evaluated for macrocells that operate at the same frequency as the Deep Space Network (DSN) and that are nearby the DSN installations. It has been found that the cell capacity is not ... -
Preemphasis Influence on Harmonic Speech Model with Autoregressive Parameterization
(Společnost pro radioelektronické inženýrství, 2003-09)Autoregressive speech parameterization with and without preemphasis is discussed for the source-filter model and the harmonic model. Quality of synthetic speech is compared for the harmonic speech model using autoregressive ... -
Using the Variable-Length Arithmetic for an Accurate Poles-Zeros Analysis
(Společnost pro radioelektronické inženýrství, 2003-09)In the paper, a reduction algorithm for transforming the general eigenvalue problem to the standard one is presented for both classical full-matrix methods and a sparse-matrix technique appropriate for large-scale circuits. ... -
W-CDMA Uplink Capacity and Interference Statistics of a LongGroove-Shaped Road Microcells Using A Hybrid Propagation Model
(Společnost pro radioelektronické inženýrství, 2003-09)The uplink capacity and the interference statistics of the sectors of a long groove-shaped road W-CDMA microcell are studied. A model of 9 microcells in a groove-shaped road is used to analyze the uplink. A hybrid model ...
