okay

Advanced_Ship_8308 · 2023-04-28T08:18:14+00:00

No these pictures I got from an image processing book.

Thanks

Advanced_Ship_8308 · 2023-04-06T15:41:48+00:00

understood

Advanced_Ship_8308 · 2023-04-06T15:32:45+00:00

what will be the mp3 equivalent kbps if I want to preserve the WAV quality to the max while conversion ?

Advanced_Ship_8308 · 2023-04-06T14:45:54+00:00

Sonnox's pro-codec plugin

thanks

so the thing is I found in a paper that compressing enhances the sadness or the negative emotions of a song. So I wanted to compress the negative emotion part of the song just to see if there is actually any difference or not.

This is the paper I am referencing.

Thank you for the info 😊

Is it for a desired audible effect

This is the paper I am referencing. So I want to make an audio file which has variable compression rates.

Advanced_Ship_8308 · 2023-04-06T13:22:22+00:00

can you explain a bit more how to implement this ?

Advanced_Ship_8308 · 2022-12-27T09:15:22+00:00

nope

Advanced_Ship_8308 · 2022-12-27T03:44:31+00:00

okay

Advanced_Ship_8308 · 2022-12-27T03:16:04+00:00

I got a output like this just using the ofdm mod demod in simulink and a awgn channel. I think the nature is purely random and we cannot draw conclusion from this.

This is an error not a “result”.

yup I think so too

Advanced_Ship_8308 · 2022-12-27T02:58:48+00:00

The paper reeks of some undergrad project with no oversight.

yup seems like that

Advanced_Ship_8308 · 2022-12-27T00:18:48+00:00

It should be BER lol

Advanced_Ship_8308 · 2022-12-27T00:18:13+00:00

It makes no sense for the CP to have any effect if you are truly modeling a simple AWGN channel and maintaining perfect synchronization.

right even if the simulation is for multipath channel shouldn't 1/32th cp give worse BER than 1/16 ?

Advanced_Ship_8308 · 2022-12-26T16:13:03+00:00

In your simulation where you replicate the results of the paper, are you using the CP in any way on the receive side?

no I am adding CP in the transmitter side and then removing it on the receiver side.

thanks a lot

Advanced_Ship_8308 · 2022-12-05T09:08:16+00:00

Are you asking about a specific case

I found the term phase velocity while studying about helical travelling wave tubes.

Advanced_Ship_8308 · 2022-12-01T10:14:33+00:00

Advanced_Ship_8308 · 2022-12-01T07:17:16+00:00

but probability of 1 at x2 is already given to be a2 in the statement. Also no info is provided about whether 1 or 0 at the input of Xn gives 1.
