JCAS#

  1# This simulation evaluates a joint communication and sensing scenario.
  2#
  3# We assume a base station communicating with a terminal using a single-carrier
  4# waveform. Simulataneously, the base-station infers spatial information from
  5# its backscattered communication signal.
  6#
  7# The simulation evaluates both the bit error rate of the downling commuication
  8# between base station and terminal as well as the probability of detection of an
  9# object within the base-stations vicinity.s
