Abstract
This technical report describes the construction of a broadband spatio-temporal channel sounder
operating at the 2.45 GHz frequency band. Based on the core 8-element receiver system provided by
the Aerospace Corp., Georgia Tech graduate student researchers Chris Durkin and Ryan Pirkl designed
and built new hardware that allows broadband RF channel sounding with increased mobility
for measurement. Key contributions include a new high-speed pseudo-random noise (PN) generator
for transmitting a broadband waveform, a vector RF signal generator for generating stable, programmable
frequencies to drive receiver hardware, and spatio-temporal data acquisition software.
This work is a continuation of the direction-finding research collaboration conducted by the
Aerospace Corp. and the Propagation Group at the Georgia Institute of Technology. The new
channel sounding system is capable of resolving multipath with up to 20 ns of time-of-arrival delay.
To demonstrate this capability, Chapter 4 presents an example measurement conducted indoors at
2.45 GHz. The measurement system is shown capturing a channel sounding waveform with 100 MHz
RF bandwidth on the 8 different antenna elements simultaneously.
