A system and method for reducing the OFDM out-of-band emissions (OOBE) and Inter-Numerology Interference (INI) in a mixed-numerology OFDM-based system by utilizing a transmitter windowing operation that smooths the inherent rectangular pulse shape of the OFDM signals. The technique retains the main design of the OFDM receivers and provides backward compatibility for the existing OFDM-based systems. The guard band and the multi-window parameters that control the guard duration are jointly optimized regarding the numerology, the use case and the power offset between the users. To fully exploit and further increase the potential of adaptive guards, an interference-based scheduling algorithm is proposed as well.

A system and method of steady-state visual evoked potential (SSVEP) frequency detection using bio-inspired filter banks (BIFB) includes, acquiring electroencephalographic (EEG) signals from a subject in response to a repetitive visual stimulus, estimating the power spectral density (PSD) of the channel of the EEG signals including at least one SSVEP response, extracting one or more SSVEP response features from the estimated PSD of the channel using a bio-inspired filter bank (BIFB) and classifying the extracted SSVEP response features to determine if the detected SSVEP response frequency from the EEG signals acquired from the subject substantially matches the repetition frequency of the repetitive visual stimulus.

In various embodiments, the present invention presents a physical layer (PHY) authentication technique for implantable medical devices (IMDs) that does not use existing methods of cryptology. Instead, a friendly jamming mechanism is established and malicious attempts by adversaries are prevented, without sharing any secured information, such as secret keys. In addition to ensuring authentication, the invention also provides advantages in terms of decreasing processing complexity of IMDs and enhances overall communications performance.
