Wireless engineering communication QAM

Click For Summary

Discussion Overview

The discussion revolves around understanding the calculation of a peak rate of 7.2 Mbps in HSDPA multicode wireless communication, specifically using 10 codes of 16 QAM modulation and a channel coding rate of 3/4. Participants are exploring concepts related to signal processing paths and seeking clarification on the problem statement.

Discussion Character

  • Homework-related
  • Exploratory

Main Points Raised

  • One participant expresses confusion about how the value of 7.2 Mbps was derived and requests hints or rewording of the question for better understanding.
  • The same participant later indicates they may have figured out the problem after rephrasing it, although they express uncertainty about their understanding.
  • Another participant welcomes the newcomer and acknowledges their progress in the forum.
  • A different participant questions the meaning of "signal processing path" and expresses uncertainty about whether they are utilizing the entire signal processing path in their approach.
  • One participant admits to having no knowledge about signal processing but welcomes the newcomer.

Areas of Agreement / Disagreement

Participants generally express individual uncertainties and seek clarification, with no consensus reached on the specific technical aspects of signal processing or the calculation method.

Contextual Notes

Participants have not fully defined the term "signal processing path," and there is ambiguity regarding the assumptions underlying the calculation of the peak rate.

Homework Statement


On a HSDPA multicode peak rate of wireless communication
Channel Coding rate: 3/4.

How was the value
7.2 Mbps found using 10 codes of a 16 QAM modulation using signal processing path.

Homework Equations


Not sure

The Attempt at a Solution


I feel bad in saying this, but I have no idea where to start. I was wondering if someone could give me some hints, or rewording the question in a way that might make it easier for me to understand.
Thanks :)

-----------------------

I think I figured out how to do it :D! I think, hopefully that doesn't change soon but since I wrote down the question here slightly different to the question asked, and then reread my question it made sooo much more sense for some random reason hahaha.
Thankss!

Haha thanks, I got to admit, it was definitely a nice way into the forum.

I was just wondering does anyone know what particular "signal processing path" means, I guess I'm just unsure if I'm actually using the whole signal processing path or not.
 
Well...I don't know anything about signal processing.:smile:
I saw you are new and just came to welcome you:-p
