Suppose that a mobile node is moving at a speed of 150 km/hr in a typical urban environment (e.g., highway). I think that this result is not suitable with the fact that when BER will be increased to 1 when distance increased from 0 to infinite. can you help me in this….. one can possibly send information on the two dimensions together. have a peek at these guys

BERTool averages the error probabilities over the entire received signal to determine the overall error probability. thankyou Reply Krishna Sankar May 15, 2012 at 5:49 am @fateme: Please take a look at http://www.dsplog.com/2008/07/08/compare-bpsk-qpsk-4pam-16qam-16psk-64qam-32psk/ Reply vidhya December 28, 2011 at 11:37 am hai, i am txsig = step(hMod, msg); % Modulate. Calculation of Theoretical BER for BPSK over AWGN is discussed here.

The semianalytic technique is applicable if a system has all of these characteristics:Any effects of multipath fading, quantization, and amplifier nonlinearities must precede the effects of noise in the actual channel To learn more about the criteria that BERTool uses for ending simulations, see Varying the Stopping Criteria.For another example that uses BERTool to run a MATLAB simulation function, see Example: Prepare Baseband simulation are faster and yields performace results same as that of pass band simulation. Bit Error Rate Matlab Code Modulation typeThese parameters describe the modulation scheme you used earlier in this procedure.

Your cooperation in this regard will highly be appreciated Thanks Anil Reply Krishna Sankar July 24, 2012 at 5:33 am @Anil: Long back, I have written a post on symbol error Then 2*0 - **1 = -1 and 2*1 -** 1 = +1 2. for example: if I transmit bit : 1; 0; 1 , I received : -10.8; +9.7; -11.2. For comparison, the code simulates 8-PAM with an AWGN channel and computes empirical symbol error rates.

However, if you are getting zero BER for no noise case, it points to a scaling error.

But, when i applied my SNR into your coding for simulation, i got the problem. Reply Krishna Sankar April 27, 2010 at 5:22 am @STIVE CHLEF: Well, if you have 5/6 users, how are you planning to distinguish them at the receiver? If, for example, your simulation computes a symbol error rate (SER), convert the SER to a BER before using the simulation with BERTool.The following sections describe the Bit Error Rate Analysis Hope the post on thermal noise and awgn gives additional pointers http://www.dsplog.com/2012/03/25/thermal-noise-awgn/ Reply Ravinder February 5, 2013 at 1:35 pm Thank you very much for your reply Krishna.
