Abstract

Subband adaptive filtering (SAF) techniques play a
prominent role in designing active noise control (ANC) systems.
They reduce the computational complexity of ANC algorithms,
particularly, when the acoustic noise is a broadband signal and the
system models have long impulse responses. In the c ....etc

When reference signal for the FxLMS algorithm is taken from an acoustic sensor convergence can be very slow due to great eigen value spread. Using a non acoustic sensor, Such as a tachometer, cancellation of narrow band noise in the sensed fundamental frequency and harmonically related ones can be achieved very fast, although other periodic noises and underline broad band noise will remain.


Backward prediction errors resulting at the various stages of an adaptive lattice predictor(ALP) represent a a time-domain orthogonalization of the ....etc

POWER SUPPLY NOISE REDUCTION USING ACTIVE RESISTORS


Introduction

Continual scaling in integrated circuit technology has made it possible to achieve higher transistor density
in a given die area. Even with the lowering of the power supply voltage for newer process nodes, the
maximum power consumption of high-end microprocessors has been projected to continue to increase for
the foreseeable

please, i need ccs code for noise cancellation

ABSTRACT
This paper explores the migration of adaptive filtering with swarm intelligence/evolutionary techniques employed in the field of electroencephalogram/event-related potential noise cancellation or extraction. A new approach is proposed in the form of controlled search space to stabilize the randomness of swarm intelligence techniques especially for the EEG signal. Swarm-based algorithms such as Particles Swarm Optimization, Artificial Bee Colony, and Cuckoo Optimization Algorithm with thei ....etc

hi
i am implementing active noise control for a duct using C 6713. i need c++ code for it. or if someone can guide me becuase i have implemented C32 DSP but implementation of C6713 is different from C32.

ACOUSTIC NOISE CANCELLATION USING ADAPTIVE FILTERING


Abstract
All the physical systems when they operate produce physical noise, which is a mixing of an infinitive number of sinusoidal harmonics with different frequencies. So, the initial signal information is corrupted with this noise. This complex signal, may be very noisy, so much that the human ear or other system which may follow it, cannot receive correct the initial signal.

Some of the earlie ....etc

I have some knowhow on noise cancellation in the receiver of radar or other communication system. But I don't know how to implement using FPGA for better result.
Now aday some projects have been performed on this area.but I am not clear about the future scope and how I can improve the scopes stated. If an MTech project proposal has been posted in IEE, I realy seek to know. ....etc
