  Radar detection and communication can be operated simultaneously in joint
radar-communication (JRC) system. In this paper, we propose a bistatic JRC
system which is applicable in multi-path environments. Basing on a novel joint
waveform, a joint detection process is designed for both target detection and
channel estimation. Meanwhile, a low-cost channel equalization method that
utilizes the channel state information acquired from the detection process is
proposed. The numerical results show that the symbol error rate (SER) of the
proposed system is similar to that of the binary frequency shift keying system,
and the signal to noise ratio requirement in multi-path environments is less
than 2 dB higher compared with that in single-path environment to reach a SER
of 10-5. Besides, the knowledge of the embedded information is not required for
the joint detection process and the detection performance is robust to unknown
information.
