The results indicate that a UWB interferer has minimal interference to the performance of IEEE 802. 11a system in line of sight scenarios, and IEEE 802. 11a can maintain reliable communication. However, in the non LOS case, a UWB interferer can severely affect the performance of IEEE 802. 11a systems; meanwhile, an IEEE 802. 11a WLAN interferer can also severely affect the performance of UWB receivers.

结果表明：在视距环境中，UWB干扰对IEEE 802.11a系统的性能影响不大，IEEE 802.11a系统可以维持正常的通信；在非视距环境中，UWB信号对IEEE 802.11a WLAN系统的性能有很大影响，同时IEEE 802.11a WLAN干扰也会严重影响UWB接收机的性能。
