Problems solved by technology

However, in the compensation method of transmission unit power of a mobile communication terminal according to the conventional art, although there is obviously a deviation according to temperature in hot summer or cold winter, only channel-based transmission power compensation according to room temperature setting is used form, so the performance of the mobile communication terminal may degrade at high or low temperatures

Embodiment Construction

[0020] In the following, a preferred embodiment of a method for compensating the transmission unit power of a mobile communication terminal will be described with reference to accompanying drawings 3 to 5, which can be based on a large temperature variation range by adding an item such as compensation value versus frequency versus temperature (item), compensating the deviation of the transmission unit power according to the channel (or frequency) according to the temperature change to maintain the flatness of the transmission unit power according to the channel (or frequency).

[0021] Fig. 3 is an example diagram illustrating a channel compensation curve and a channel compensation table of a mobile communication terminal operating at room temperature; Transmission unit power compensation table. The transmission unit channel compensation curve and the transmission unit power compensation table can be obtained by a program using a power measuring instrument capable of measuring...

Abstract

A method for compensating power of a transmitter is provided to prepare transmitter channel compensating tables for a CDMA transmitter, and to compensate CDMA transmission power according to temperature and a channel, thereby optimally maintaining the transmission power of the transmitter. A system prepares transmitter power compensating tables by channel corresponding to a predetermined temperature region. A CDMA transmitter decides used temperature and a channel, and obtains a compensation value from one of the transmitter power compensating tables for the temperature region, based on decided values. The CDMA transmitter compensates transmitter power with a reference value by using the obtained compensation value. The transmitter power compensating tables by channel corresponding to the predetermined temperature region are prepared, based on transmitter channel compensating curves measured at high temperature.

Description

technical field [0001] The present invention relates to a method for compensating the power of a transmission unit of a mobile communication terminal, in particular to a method for compensating the power of a transmission unit of a mobile communication terminal capable of maintaining the power of a transmission unit through a channel without considering the power of the mobile communication terminal Operating temperature. Background technique [0002] FIG. 1 is a functional block diagram illustrating a general mobile communication terminal. [0003] As shown in Figure 1, mobile communication terminal comprises: antenna 10, RF (radio frequency) unit 20; IF (intermediate frequency) unit 30; BBA (baseband analog) unit 40; Baseband modem 50; And IO (input / output) unit 60. [0004] Here, the RF unit 20 converts the modulated carrier between high frequency and intermediate frequency, the IF unit 30 converts intermediate frequency and baseband, and the BBA unit 40 converts the bas...
