Under all launched optical powers, the performance of the P-CFNN equalizer is the best among all comparison algorithms, and the maximum ΔQ-factor compared to without employing the nonlinear compensation algorithm reaches 3.94 dB. Meanwhile, an equivalent real-valued fully connected neural network (RFNN) with the same time complexity as a CFNN is proposed for fair performance comparison. What we believe to be a novel complex principal component analysis (CPCA) algorithm applied to complex-valued fully connected neural network (CFNN) is designed to further reduce the computational complexity of the model. In this paper, we proposed a complex principal component analysis-based complex-valued fully connected neural network (P-CFNN) model aided by perturbation theory and demonstrated it experimentally on a dual-polarization 64-quadrature-amplitude modulation coherent optical communication system. I'll freely admit that I do like all those "cool" dancing lights that, IMHO, made the 80's stereo cool.An increasing number of scholars have proposed many schemes to mitigate the Kerr nonlinearity effect restricting the transmission capacity of optical fibres. Again, IMHO!!Īgain, I know the value on this specific Kenwood equalizer isn't that great or that it's even a classic piece of equipment, but it has some deep sentimental value to me and something that will not be thrown out.

I'm also hoping to find a good condition Akai GX-747 in black some day soon.Īgain, I know the value on this specific Kenwood equalizer isn't that great or that it's even a classic piece of equipment, but it has some deep sentimental value to me and something that will not be thrown out. Which also will be sent in for a cleaning and a "tuned up" as well. Once I complete this move, I'm hoping to hook up this Kenwood equalizer to my Yamaha MX/CX/TX 1000 and several other late 80's DBX 3 band range expander and noise reduction units. With that said, is it possible to have the light fixed back to their factory brightness or at least very close? I'm pretty sure if its possible, it wouldn't be a cheap process, but I would seriously consider any repairs, even at an upper level of cost. I know of the different views on EQs and respect both the pros and cons of them, but this piece of equipment has a special place in my heart and would like to keep it around and functioning for the foreseeable future. I checked the display function switch/button and it's not the source of the problem. I purchased it new back in 1996/97 new, but its been in storage for close to 10 years now and prior to that, only seen very light usage. While packing up all my stereo equipment that's been in storage for a cross country move, I noticed that the LED (?) display lights on my Kenwood GE-7030 EQ is very-very dim and not having a uniformed brightness throughout the display screen. This is a repost from the General Discussion forum where it was originally posted, but didn't receive any responses to my question relating to the Kenwood GE7030 equalizer.
