This paper presents the convergence analysis result of the discrete cosine transform-least-mean-square (DCT-LMS) adaptive "ltering algorithm which is based on a well-known interpretation of the variable stepsize algorithm. The time-varying stepsize of the DCT-LMS algorithm is implemented by the modi"ed power estimator to redistribute the spread power after the DCT. The performance analysis is c...

The so-called semi-blind source separation (SBSS) is an extension of BSS when some signals can be directly and individually measured. SBSS can be used to implement multi-channel acoustic cancellation (MCAEC) without the need for double-talk detection. However, traditional MCAEC approaches based on least mean-square (LMS) lead to a non-unique solution due to correlated sources formed when a sing...

Ghost circuitry (GC) insertion is the malicious addition of hardware in the specification and/or implementation of an IC by an attacker intending to change circuit functionality. There are numerous GC insertion sources, including untrusted foundries, synthesis tools and libraries, testing and verification tools, and configuration scripts. Moreover, GC attacks can greatly compromise the security...

Abstract—This paper considers detection techniques for unresolved Ricean/Rayleigh fading multipath channels. It is wellknown that the optimal receiver has an estimator-correlator form, with a Minimum Mean-Square Error (MMSE) estimate. With known multipath delays and unknown specular phases, the Ricean non-coherent multipath channel is a case where the received noiseless signal process is non-Ga...

Current chronic diseases are a reflection of the westernized diet that features a decreased consumption of dietary fiber. Indigestible dietary fiber is metabolized by gut bacteria, including Faecalibacterium prausnitzii, to butyrate, which has a critical role in colonic homeostasis owing to a variety of functions. Dietary fiber intake has been significantly inversely associated with the risk of...
