The implementation of a feedback ANC applied to a headset was done using a low cost, 16 bits, fixed point DSP StarCore MSC7116 from Freescale. The DSP program runs over SmartDSP (RTOS). The board has also integrated the stereo 16 bit CODEC AK4554. The noise inside the headset may vary over time because the external noise has changed, or because the headset has moved, changing its acoustic transfer function. The ANC system must be able to adapt to these changes, modifying the produced anti-noise signal accordingly. The ANC adaptive filters are made of a Finite Impulse Response (FIR) filter with varying coefficients. In order to compensate the effect of S(z) the input to the adaptive algorithm has to be affected (filtered) in the same way as the controller´s output. The modified algorithm is then called Filtered x Least Mean Squares (FxLMS) algorithm. As S(z) is unknown and may vary on time, it is identified by a second adaptive system and a copy of its transfer function, S^(z), is intr

FPGA prototyping and write memory BIST and boot loader code for openMSP ASIC project.
Fernando has been a real pleasure to work with on this project. He's very meticulous in his work which is a critical attribute to being a successful engineer/consultant. He's capable of high quality deliverables along with excellent documentation/communication skills. I will continue to leverage his expertise in the future provided he enjoys the work he is doing for Power Down Semiconductor as the relationship has to work both ways.

This guy is the best at what he does, when he says he will deliver to a standard beyond your expectations this is without a doubt an understatment - price is therefore justified completley and he is a very flexible and easy communicator, very proffessional and friendly - if he has a skill set you are looking for he is your guy!

Write somewhat complex VHDL code to be tested on Altera DE2 board
Fernando is very thoughtful with his approach and asks many questions to ensure you are getting what you need. He produced a quality VHDL code for me and I am very satisfied. I will definitely look for Fernando if I need more coding work completed.

Super efficient and trustworthy . You won't have to worry with his deep knowledge and understanding of coding. He delivers everything that i needed with guidance too. I initially hired a freelancer with 60+ reviews but he didn't complete my job as agreed and mia-ed. Eventho Fernando has only 3 reviews but his standard and level of work is really professional. I recommend him to all of you out there that needs help on hardware programming. Thanks again.

FxLMS and MFxLMS Stability Constrains when used in Active Noise Control

IEEE
This paper presents a comparison of the stability of the MFxLMS and FxLMS algorithms, applied to the low frequency narrowband Active Noise Control (ANC). This work focuses on the study of the secondary path in a headset, and the effect of its variations in the system's stability. The analysis is completed with simulations that support the conclusions. https://ieeexplore.ieee.org/document/6502805

Adaptive Narrowband ANC, Design and Implementation Issues

IEEE
This paper presents the design and implementation of an adaptive feedback Active Noise Control (ANC) to cancel the low frequency narrowband noise remaining inside a headset shell. The implementation issues were addressed and tested on a commercial fixed point Digital Signal Processor (DSP). https://ieeexplore.ieee.org/abstract/document/5993725
