Description

The Commission has also adopted a proposal for a directive on the protection of workers from risks related to exposure to ionising radiation.
The invention relates to new training sequences with optimized cross-correlation for use in cellular mobile communications.
The Technical Standards
Err1:Expecting ',' delimiter: line 1 column 288 (char 287)
The following shall be deemed to be the case:
The present invention is based on the task of developing sequences with equally favourable autocorrelation properties but improved cross-correlation properties. Of course, these effects can also be represented in other number systems.
The invention thus consists in the use of the following: The Commission has also been asked to provide a detailed description of the training programmes in the field of mobile communications.
The following is a brief description of the drawings:
The invention is illustrated by drawings showing: Fig. 1 the auto and cross correlation properties of the known GSM training sequences; and Fig. 2 these properties of the training sequences according to the invention.
The best way to do this is to use the following formula:
Figure 1 shows the normalised autocorrelation (AKF) of the training sequence TS0 and the normalised cross-correlations (KKF) of the sequences TSO-TS1 and TS0-TS2.
Figure 2 shows the autocorrelation (AKF) of the new sequence TSn0 and the cross-correlation (KKF) of the sequences TSn0-TSn1.While the autocorrelation function shows no difference between the conventional and new training sequences, the cross-correlation of the new sequences is both smaller and more evenly distributed, which leads to higher reliability in the use of these training sequences in GSM, especially for adaptive antennas and room multiplexes.
