Does anyone knows what is Enright Periodogram algorithm is?

I know that Enright Periodogram algorithm is a way to find the suitable period of signal with a lot of noise.

in general i know that the method is based on dividing the time series signal into the blocks of expected period and than performing the calculation

BUT: what to do if the signal cannot be divided into blocks of expected period and there is a residue ? for example: if to sample the signal every hour for 27 hours- so the time series would be a vector and his length is 27 after that to check if the sampled signal has either periodicity of 4 hours or 5 hours. if to check the periodicity of the 4 hours the time series will be divided into 6 blocks of 4 and there would be a residue of 3(4*6+3=24+3=27)

and if to check the periodicity of the 5 hours the time series will be divided into 5 blocks of 5 and there would be a residue of 2(5*5+2=25+2=27)

so every time there is could be a different residue that can affect the calculation,so if anybody knows what is the convention for this problem in Enright Periodogram calculation, please tell(i mean write) me !

This is hardly a Matlab problem, so this is probably not the best forum to ask this question. This is a research question. Your best bet would be to see who has cited Enright. There seems to be 67 other papers that cite it.
