Method for estimating communication conditions affecting an UWB wireless link

A telecommunication system comprising:

• a transmitter configured to transmit data in a radio signal including a pulse sequence;
• a receiver including a decoder configured to determine a threshold value based on a bandwidth of the pulse sequence, and decode a power value representative of an amount of power carried by the pulse sequence;
• a comparing unit configured to compare said power value to the threshold value;
• and
• an estimating unit configured to estimate
• a first parameter representative of noise affecting the transmission of the radio signal, and
• a second parameter representative of an amount of power which would be carried by each pulse sequence in the absence of noise,
• wherein the estimating unit is configured to estimate the first parameter and the second parameter before the decoder determines the threshold value.
