Compensation of a Non-ideal UWB Antenna Performance

摘要

Non-ideal hardware degrades the performance in UWB systems. Especially the non-isotropic transmit antenna is critical: To meet the regulation, the maximal antenna gain must be substracted from the regulation which leads to reduced transmit power, and hence decreased signal-to-noise-ratio. This contribution briefly describes the modeling of a complete, non-ideal impulse radio system and, based on this, shows strategies to improve the performance. This includes optimal pulse design with joint compensation of the frequency response of the non-isotropic transmit antenna. For this two different compensation methods are presented. An UWB communication system simulation delivers the achievable bit error rates and clearly shows the improvement by the compensation measures.
