Patent ID: 7539267

Claim:
A method for signaling in an ultra wide bandwidth communications system, comprising: generating a sequence of data symbols; transmitting sequentially, for each data symbol, a set of reference pulses, in which the set includes a plurality of reference pulses and each reference pulse being of a different type; transmitting sequentially a set of data pulses, there being one data pulse for each corresponding reference pulse, a type of each data pulse being identical to the type of the corresponding reference pulse, in which the set of data pulses are transmitted after the set of reference pulses; receiving the set of reference pulses and the set of data pulses, in which the set of data pulses are received after the set of reference pulses; filtering each data pulse according to a matching template pulse specific for the type of the corresponding reference pulse; and multiplying each filtered data pulse by a delayed version of the received data pulse to recover the data symbol, and in which received data pulse is weighted according to the pulse type.
