Method and apparatus for simultaneous power estimation of multiple signal sources in communication system

A power estimation apparatus comprising:

• a processor;
• a memory electronically communicating with the processor;
• a fixed antenna;
• a mobile antenna;
• and
• instructions stored in the memory,
• wherein the instructions, when executed by the processor, operate to cause the power estimation apparatus to:
• perform a first operation of obtaining N measurement values by receiving a signal from signal sources using the fixed antenna and the mobile antenna that moves at a speed v from a first point to an Nth point;
• perform a second operation of generating a two-dimensional (2D) data collection set comprising N×M measurement values, by repeating the first operation M times;
• apply an approximation singular value decomposition (SVD) algorithm to the 2D data collection set;
• and
• obtain information of the signal sources based on an application result of the approximation SVD algorithm,
• wherein N and M are natural numbers.
