Moreover, the antenna subsystem design with co-channel self-interference reduction is required to ensure the low noise amplifiers and other actives in the chain do not overload. The prevailing thought is that the solution to the self-interference challenge is the combination among several approaches including: (i) antenna design (ii) analog cancellation, for example through RF frontend design as its wider dynamic range and sensitivity is of crucial importance (iii) digital cancellation In the context of STAR systems with maximum utilization of resources, applying one of these approaches is not sufficient to achieve the level of self-interference cancellation that leads to a workable system.

Moreover, wideband self-interference cancellation is more challenging than narrowband designs, leaving significant rooms for research before modern wideband radio communications can take full advantage of in-band full-duplex radios. The higher transmitted power and narrower communication channel the greater are the isolation requirements, in some cases more than 150 dB. However, the implementation of in-band full-duplex systems is challenged by self-interference between the strong transmitted and the weak received signal at each transceiver device. These systems, also known as simultaneous transmit and receive (STAR) systems, have potential to increase spectral efficiency by either doubling the number of users or by doubling the communication channel capacity for each user in the same frequency interval allocated for half-duplex communications.
On the other hand, in-band full-duplex systems that transmit and receive simultaneously in the same frequency band overcome some of these issues. Physical separation between the transmitter and receiver, with electromagnetic shielding or attenuation material placed in-between, can lead to their simultaneous operation in time and frequency however, additional required space is often not available. This leads to underutilization of available resources and inefficient flow of information between wireless systems. Most communication systems are half-duplex and they use separate bands or time slots to transmit and receive signals. The frequency spectrum is congested due to usage on the part of many communication systems and a few radar and military systems.
