In this paper, phase variation value is defined with help of calculating error energy of adjacent code cells of MPSK signal, so that recognition of MPSK signal phase encoding rule can be realized.

I'm using Groovy's syntactic sugar to execute a code block, which is to place a set of parentheses adjacent to the code block's variable.

Restrictions: the code restricts free areas of 6 meters at the front overlooking the lake, 7 meters at the back adjacent to the golf course, and 5 meters along the lateral party wall.
