Download free e-book on error probability in AWGN

by Krishna Sankar on October 1, 2008

We have quite a few articles discussing bit and symbol error rates for popular digital modulation schemes in Additive White Gaussian Noise (AWGN) channel. This post summarizes the articles discussing the theoretical and simulated error rates for the digital modulation schemes like BPSK, QPSK, 4-PAM, 16PSK and 16QAM. Further, Bit Error Rate with Gray coded mapping, bit error rate for BPSK over OFDM are also discussed.

The links to the individual articles and the Matlab/Octave simulation models are listed below. Alternatively, I have made a e-book discussing all the below mentioned articles to a single PDF file. If you wish, you can download the free e-book by subscribing to the free email newsletter.

The links to articles discussing and the Matlab/Octave simulation models are listed below.

Bit error probability for BPSK modulation

$P_{s,BPSK}=\frac{1}{2}erfc\left({\sqrt{\frac{E_b}{N_0}}}\right)$ .

Click here for Matlab simulation for bit error rate (BER) curve with BPSK modulation.

Symbol error rate for 4PAM

$P_{s,4PAM}=\frac{3}{4}erfc\left({\sqrt{\frac{E_s}{5N_0}}}\right)$ .

Click here for Matlab simulation for symbol error probability with 4PAM modulation

Symbol error rate for 4-QAM (QPSK)

$\begin{eqnarray}\mathbf{P}_{s,4QAM} = erfc\left({\sqrt{\frac{E_s}{2N_0}}}\right)\end{eqnarray}$

Symbol error rate for 16-QAM

$P_{s,16QAM}=\frac{3}{2}erfc\left(\sqrt{\frac{E_s}{10N_0}}\right)$

Click here for Matlab simulation of symbol error rate curve with 16QAM modulation

Symbol Error Rate for 16PSK

$P_{s,16PSK}=erfc\left[\sqrt{\frac{E_s}{N_0}}sin(\frac{\pi}{16})\right]$ .

Click here for Matlab simulation for symbol error rate with 16PSK modulation

Note: The formula derived in the post is for a general M-PSK case. For an M-PSK scheme, the symbol error rate is,

$P_{s,MPSK}=erfc\left[\sqrt{\frac{E_s}{N_0}}sin(\frac{\pi}{M})\right]$ .

Simulate 8-PSK (k = 3, M = using the mapping below:
There is no need to generate individual bits. The input to the detector is r = s + n where all numbers are complex. The input, s, is a complex number with magnitude A and phase
determined by the random input. To generate complex noise, you need two independent
Gaussian random variables. Alternatively, you can model all signals as two-dimensional
vectors. The detector finds the closest signal point to r.
For this simulation, SNRb = (A^2)/6. Simulate the performance the system for SNRb = 7, 8,
9, 10, 11 dB and find the symbol and bit error rates. The printout format is:
System:8-PSK; SNRb=___(dB); #Bits transmitted=___ (i N/10, i = 1,…,10); SER=___; BER=___
Compare your results with the theoretical estimates of symbol and bit error rates. Plot the
theoretical estimates (curves) and the simulated error rates (points) in one figure.

Dear Mr.Krishnapillai,
I admire your dedication and sincerity in helping others by giving useful suggestions, ample guidance and valuable advises. I am doing research in communication field and topic is to improve the performance of ofdm systems. my plan is to minimise PAPR and Frequency offset by using scrambling(PAPR Redn) in Txr and Windowing in Rxr(ICI Cancellation), plz comment on this and if you have any suggestion it will defenitely help me.

63 Krishna Pillai May 31, 2009 at 8:25 pm: @Bijunair: Well, even I have not done much on PAPR reduction rather than using scrambling at the transmitter. Am curious about how you are going to reduce the effect of frequency offset by using windowing in receiver. You may point me to some references which you are using. Thanks.

Hi,

I have already ask you the question about the calculation of uncoded BER for the pulse position modulation and ergodic capacity calculation using any fading channel(lognormal or gamma). please reply

140 Krishna Sankar January 28, 2010 at 5:31 am: @Amjad: Sorry, I need more study to reply to your queries. And due to time constraints, am unable to allocate time. Kindly excuse.
