Decomposition Measurement for Antenna Gain and Radio Sensitivity of Wireless Receiving System

A general procedure for decomposition measurements for receiver antenna gain and radio sensitivity based on received signal strength indicator (RSSI) reporting is proposed in this paper. This procedure standardizes the measurement steps for eliminating nonlinear error in RSSI reporting. After path loss calibration and RSSI uncertainty calibration, the real performance of the antenna and the radio working in the actual environment of wireless receiving system can be measured. The antenna gain is obtained from the difference between RSSI reporting and transmit power, and the radio sensitivity is obtained from the transmit power. This method helps to improve the development efficiency of radio devices and shorten the development cycle. The general procedure is suitable for single-input single-output (SISO) wireless receiving system having RSSI reporting such as GSM, and Bluetooth systems.
