In this paper, we present a bitwise metric generating function for a binary reflected Gray coded (BRGC) M-PSK signal by means of coordinate rotation. Using the properties of the BRGC mapping, we minimize the number of coordinate rotations. The proposed function does not rely on channel state information (CSI), and provides low implementing complexity.
