Abstract
The invention relates to a spatial diversity receiving device and an input channel switching method. The device comprises a main control circuit and at least one receiving channel including a RF selective switch, wherein the circuit controls the switch, so as to select one of the plurality of input signals from the plurality of antennae and send that signal to a receiving module. The module comprises a RSSI unit for outputting a RSSI value and sends the value to the circuit. On basis of a real time analysis to the receiving signal, the circuit selects a predetermined occasion to perform a compulsive switching and dynamically selects the antenna with a stronger signal so that the generation of error code due to transient interference may be reduced. The system exhibits an excellent resistance to wireless signal fading, and has a simple structure as well as a low cost and power consumption.
