I have read some papers for UWB modulation, because i am not a student for communication engineering , i don't understand clearly about the modulation scheme about UWB
There are two different groups for supporting their own modulation scheme, one is based on CDMA supported by Motorolla, the other is OFDM supported by Intel et al, i wonder whether Impulse radio systems is given up . or The carrierless style is given up, now the standarization for 802.15.3a is based on carrier modulation,
Therefore, is there something useless for us developing RF system based on impulse radio?
