Ultra-wideband (UWB) communication systems and apparatus are provided. One embodiment of an UWB receiver may include a first antenna that receives UWB pulses, and a second antenna that also receives UWB pulses. The UWB receiver also includes a delay element communicating with the second antenna, with the delay element delaying the UWB pulses received by the second antenna. A combiner in the receiver then combines the UWB pulses received by the first antenna with the delayed UWB pulses received by the second antenna. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
