Problems solved by technology

However, the execution of the audio application should not last more than a few seconds, because there is such a danger that the wireless terminal loses the connection with the mobile communication network
The time limit may be sufficient for recognition of short voice commands, but this period of time is often not sufficient for storing and listening to recordings, for example
[0009] In the above, the audio application was presented only as an example, but corresponding problems may also arise in other applications: in these other applications, a lot of real-time processing is required during the measurement of the base station signal

Embodiment Construction

[0016] In the simplified block diagram, figure 2 There is shown a wireless terminal 1 complying with the preferred embodiment of the present invention. The wireless terminal 1 comprises a control block 2 which advantageously comprises a digital signal processing unit 3 (DSP) and a processor 4 such as a micro control unit (MCU). The control block 2 can also contain: a memory 5, one or more analog-to-digital converters 6 (ADC) and interface logic 20 (I / O, input output). The control block is realized by, for example, an Application Specific Integrated Circuit (ASIC) or the like. However, it is obvious that the control block can also be realized as a separate functional block. The wireless terminal 1 also comprises mobile station means 7 such as a transmitter 8 and a receiver 9 . The wireless terminal 1 additionally comprises a user interface 10 which advantageously comprises a display 11 , a keypad 12 , a microphone 13 and a headset 14 . Obviously, instead of or in addition ...

Abstract

The invention relates to a method for performing measurements in a wireless terminal (1) comprising a receiver (9) for receiving radio frequency signals, means (6) for taking samples (i, q) from the received signals and means (3) for performing measurements on the basis of said samples (i, q). The samples taken from the received signal are stored. Measured values are calculated (301) for the stored samples (i, q) after a set of samples (i, q) has been stored.

Description

technical field [0001] The invention relates to a method for performing measurements in a radio terminal comprising a receiver for receiving radio frequency signals, means for generating samples from the received signal and for performing Measuring device. The invention also relates to a wireless terminal comprising a receiver for receiving radio frequency signals, means for generating samples from the received signal and means for performing measurements based on said samples. Furthermore, the invention relates to a system comprising a wireless terminal comprising means for receiving a radio frequency signal of a receiver, means for generating samples from the received signal and means for performing measurements based on said samples device. Background technique [0002] In a mobile communication system, wireless terminals are connected to a mobile communication network via one or more base stations to receive and make telephone calls, for example. The wireless terminal...
