Abstract :
In certain cases, impacts linked to the transmission channel have to be precised. This is the case when it is question to study the contribution in terms of needs, consumption and size of the Channel Estimator in the Low cost and low power ASIC´s Digital Signal Process working at equivalent frequency equal to 40 GHz. Thus, in this paper the path loss in the case of ground reflection is studied, according to the ECC and CEPT frequency and power limitations. It allows quantifying the path loss contribution, the Signal to Noise Ratio (SNR) degradation and particularly the Intersymbol Interference (ISI) between signal and echoes in the case of very high speed UWB transmission, only few nanoseconds average repetition interval, short range transmission (0-1 m) and short pulse power. Impacts of those echoes are discussed.
