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?
Many Thanks

The RMSE calculation remains the same. You need to take the diferences, square them, accumulate them, take the mean, and the the square root of that.

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));
