A method for improving the dynamic range of frequency-modulated continuous-wave (FMCW) radar systems is presented. Bright echo signals detected with FMCW radars can carry strong phase noise sidelobes, especially at W-band and higher frequencies where extremely quiet local oscillators do not exist or are practical. These sidelobes hide targets that would otherwise be detectable by radar. Owing t...

Frequency and timing of digital clocks, digital switching activities, and number of transistors in digital blocks are the key behavior-level parameters to model switching noise generated by complicated digital systems. In this paper, a Digital Noise Emulator (DNE) is implemented on a test chip to study how these parameters impact the performance of a ring-typed-VCO-based PLL. In addition, the p...

Code Division Multiple Access (CDMA) system is being most popular communication technique due to its robustness & spread spectrum techniques. The CDMA include the pseudo sequences (PN-sequences) which provide the secure communication over a wide band. But the Multiple Access Interference (MAI) limits the capacity of Direct Sequence Code Division Multiple Access (DS-CDMA) based systems. For DS-C...

To enhance speech intelligibility for people with hearing loss, aids will amplify using gains derived from evidence-based prescriptive methods, in addition to other advanced signal processing mechanisms. While the evidence supports use of aid intelligibility, these adjustments can also be detrimental sound quality, poor quality cited as a barrier device adoption. In general, an uncontrolled env...
