Abstract
An antenna diversity receiver includes a plurality of antennas, an antenna selector unit, an RF module unit, a logic gate unit, a power detector unit, and a selection controller unit. The antenna selector unit selects one of the antennas. The RF module unit converts an RF RX signal received from the antenna selector unit into a baseband RX signal. The logic gate unit controls a power detection mode for detecting the power levels of RX signals and an operation mode for selecting one of the antennas. The power detector unit detects the power level of the RX signal. The selection controller unit controls the antenna selector unit to sequentially select the antennas in the power detection mode, and controls the antenna selector unit to select the antenna with a relatively good RX sensitivity among the antennas.
