AB  - Ultra wide-band (UWB) short-range communication systems are valuable in medical 
      technology, particularly for implanted devices, due to their low-power 
      consumption, low cost, small size and high data rates. Monitoring of neural 
      responses in the brain requires high data rate if we target a system supporting a 
      large number of sensors. In this work, we are interested in the evaluation of the 
      capacity of the ultra wide-band (UWB) channel that we could exploit using a 
      realistic model of the biological channel. The channel characteristics are 
      examined under two scenarios that are related to TX antenna placements. Using 
      optimal power spectrum allocation (OPSA) at the transmitter side, we have 
      computed this capacity by taking into account the fading characteristics of the 
      channel. The results show the pertinence of the optimal power spectrum allocation 
      for this type of channel. An improvement by a factor of 2 to 3 over a uniform 
      power spectrum allocation (UPSA) when the SNR <; 0 dB was obtained. When the SNR 
      is > 40 dB, both approaches give similar results. Antennas placement is examined 
      under two scenarios having contrasting power constraints.
