dc.description.abstract |
This paper presents the implementation of a twodimensional
(2-D) finite-impulse-response (FIR) trapezoidal filter
based beamforming array receiver. A 2.4 GHz 16-element receivemode
IQ array is designed and used for physically measuring the
beam patterns corresponding to 2-D FIR trapezoidal filters. The
16-element beamformer is implemented using the reconfigurable
open architecture computing hardware version-2 (ROACH-2)
field programmable gate array (FPGA) platform to perform
analog to digital conversion and digital signal processing. The
2-D FIR trapezoidal filter is designed as a 16-spatial input 32-
tap filter and is implemented targeting the ROACH-2’s Xilinx
Virtex 6 (sx475t) FPGA chip as a filter-and-sum architecture.
The receiver array is precisely rotated (keeping the transmitter
fixed) to digitally measure the received energy by integrating the
instantaneous power of the output of the 2-D FIR trapezoidal
filter for each angle of reception. The main lobe of the measured
beam pattern is well aligned with the simulated beam pattern,
and the highest measured side-lobe level is −17.8 dB. |
