摘要： A spread spectrum communication system includes a first and a second antenna, a first and a second radio frequency demodulator, a first and a second analog-to-digital converter, a first and a second filter, a clear channel assessment device, and a selection device. The radio frequency demodulators convert radio frequency signals to baseband signals, respectively. The analog-to-digital converters convert baseband signals to digital signals, respectively. The filters filter the first and second digital signals to generate filtered signals, respectively. The clear channel assessment device generates a channel assessment signal and a path selection signal according to signal characteristics of the filtered signals. The selection device refers to at least one of the channel assessment signal and path selection signal to selectively output one of the filtered signals, or generate no signal output.
