AI Technical Summary

Benefits of technology

In summary, this technology reduces interference caused during transmissions due to signals sent over multiple paths simultaneously. By comparing two parts of messages together, less communication occurs but there may even exist one if another path has been used for sending packets correctly. Additionally, this technique allows for faster detection times without requiring any extra steps like searching within specific time windows. Overall, this method improves efficiency and reliability in wireless networks while reducing delays.

Problems solved by technology

Technical Problem: Current Wireless Communicating Systems use comparative testing techniques to compare between specific sequences called reference words and unknown ones. These systems require multiple times during their operation cycle when comparing different bases. Additionally, they often perform tests repeatedly until there are sufficient matching patterns being discovered without repeating them.

Embodiment Construction

[0053] best practice

[0054] Figures 1 to 5 have already been described in the preamble of this specification.

[0055] The embodiments to be described hereinafter are based on a DECT system which according to the invention comprises a mobile station equipped with a receiving device, storage means, a comparing device and a synchronizing device according to the invention .

[0056] First, the comparison device of the mobile station will be described in detail. This comparison device is in Figure 6 is shown graphically.

[0057] The comparing devices include a first comparing device 61 and a second comparing device 62 . The input of the first comparing device 61 and the input of the second comparing device 62 are connected in parallel to a receiving device (not shown) of the mobile station. The output of the first comparison device 61 is connected via a counter 63 to a first input of an AND gate 64 and the output of the second comparison device 62 is directly connected to a

Abstract

The invention relates to a method of synchronizing a mobile station with a base station in a wireless communications system, to a mobile station for a wireless communications system, as well as to a wireless communications system of this kind. In order to enable faster ultimate synchronization, it is proposed to compare components of the received data not only with a stored synchronization pattern, but also with a stored identification pattern prior to the adaptation of the timing of the mobile station to received data. Already before the synchronization it can thus be determined with a high degree of probability whether received data originates from a desired base station or not. The necessity of checking the contents of packets which are not associated with a desired base station can thus be avoided. Moreover, because of such preliminary checking, it is no longer necessary either to reset the timing of the mobile station after synchronization on the basis of data which later appear to originate from another base station.
