Probability Of Error 4 Pam

ComparedOEMs traditionally used DSP-based hardware, plugged into a PC, for motion control. But new software-based solutions have challenged this approach, claiming equal or better performance at lower cost.View Forums comp.dsp Error-rate 2-PAM Vs. m-ary pam modulation 4-PAM Started by drgz ●April 25, 2008 ChronologicalNewest First Hello, just got a small m ary pam probability of error question about how to calculate the error-rate for the two different cases. I'm working on a school project where I'm
Pam Bit Error Rate
testing 2-PAM vs. 4-PAM over an AWGN-channel with a fixed SNRdB = 10dB in both cases. After running several tests in both C (ansi) and Matlab, it seems like that the 4-pam system
Symbol Error Rate Definition
got something between 50-100 times the error-rate of the 2-pam system. But how do i prove this mathematically? Since the SNRdB is fixed to 10dB, and the symbol variance to 1, I get that the decision levels for the 4-PAM case are -2*k, 0 and +2*k, where k = 1/sqrt(5). But how do I do the rest? I assume I have to calculate the areas of 4-pam ber the tales on the Gaussian curves for each case, but when I do that I dont get any answer that makes me any smarter, at least not any answer backing up the numbers I get when I run the code for the system in each case. Anyone who could help me into the correct direction here? - drgz Reply Posted by ●April 25, 2008On Apr 25, 6:56 am, "drgz"
