About this topic:
Previous works on bistatic integrated sensing and communication (ISAC) systems have primarily investigated fundamental trade-offs arising from sharing transmitter resources between sensing and communication signals. However, ISAC trade-offs associated with the use of integrated multi-antenna receivers, where sensing and communication signals mutually interfere, have received comparatively little attention.
In this webinar, our presenter will investigate bistatic ISAC architectures, and related system design aspects in which the transmitter and/or the receiver operate as ISAC entities. He will analyze the resulting transmitter- and receiver-side trade-offs and characterize the achievable sensing and communication performance. Particular emphasis is placed on an important design aspect of ISAC systems, namely the separation of sensing and communication signals at the transmitter through precoding.
He will consider a practically relevant setting in which the multi-antenna sensing receiver does not have access to the communication symbols, while the communication receiver performs minimum mean-squared error symbol estimation under pilot-assisted imperfect channel state information. Within this general framework, we show that both deterministic sensing symbols and stochastic communication symbols contribute to the Fisher information at the sensing receiver. This leads to a more intricate Fisher information structure and Pareto boundary than commonly assumed in ISAC studies and reveals a previously unexplored form of the random–deterministic trade-off in bistatic ISAC systems.
