Problems solved by technology

Therefore, the U.S. FCC specifically stipulates the highest limit of UWB transmission power spectral density to reduce UWB interference to shared communication systems, but UWB is also interfered and threatened by various communication systems, especially when the radiation power of these interference sources is much greater than When the UWB signal power is high, UWB receives serious interference, so interference suppression is essential for UWB communication systems

Abstract

The invention relates to a method for suppressing ultra-wideband pulse radio interference based on a correlated receiver template design. The method comprises: S1, estimating an interference signal toobtain a frequency band of the interference signal; S2, according to the frequency band of the interference signal, carrying out correlated receiver template designing; S3, transmitting an ultra wideband useful signal and carrying out correlation on a receiving signal by using the template designed at the S2 at the correlated receiver side; and S4, carrying out sampling decision making on the correlated result from the S3 to obtain corresponding output signal sequence. Therefore, the interference can be suppressed effectively.

Description

technical field [0001] The invention relates to the field of broadband wireless communication, in particular to a method for suppressing ultra-wideband pulse radio interference by adopting related receiver template design. Background technique [0002] One of the realization technologies of Ultra Wideband (UWB for short) wireless communication is impulse radio. Pulse radio uses ultra-short time pulses to generate signals with ultra-wide (GHz) bandwidth, and has high system throughput for short-distance communication. Since UWB basically covers the frequency bands of various existing communication systems, it needs to coexist with many existing communication systems, for example, coexist with the IEEE 802.11a wireless local area network working at 5Ghz. Therefore, the U.S. FCC specifically stipulates the highest limit of UWB transmission power spectral density to reduce UWB interference to shared communication systems, but UWB is also interfered and threatened by various com...
