Single Receiver Multi-antenna Code-Modulated IR-UWB Front-End
Abstract : The multi-antenna receiver has many use
cases in wireless communications and Radar but it faces
some major drawbacks such as high cost of hardware and
high power consumption. Recent developments on narrow
band systems have led to an alternative solution called
Code-Division Multiplexing (CDM), using a single RF
receiver front-end to receive signals from multi-antenna.
For this purpose signals from the antennas are mixed
with high speed spreading codes and then are combined
at the RF stage. However, the use of high speed codes
increases the signal bandwidth. Applying this solution on
Ultra-Wide Band (UWB) systems is questionable because of
the bandwidth increase. This paper discusses the principles
and implementation of CDM technique on an Impulse
Radio (IR) UWB system showing interesting insights. An
experiment is performed to estimate the Angle-Of-Arrival
(AOA) on the recovered signals in a basic indoor positioning
scenario.
