RMSE between original and predicted values.

If I have thousand samples of my signal in a vector form like 1*1000, and I will predict my signal at each iteration that results into 1*1000 also. Then In this case, how will I find the RMSE of my model?

Without any other information, the maximum likelihood prediction for every element would be the mean of the entire signal. But it seems you'd rather have the rms, so you'd have
RMSE = rms(yourVector)
predictionVector = RMSE * ones(length(yourVector));
