Comments on "Binary CPSK Performance Analysis for Saturating Band-Limited Channels"

This correspondence is to point out an error that appeared in the paper (ibid., vol. COM-27, pp. 596-603, Mar. 1979), which claims that the expression of eq. (2) is the first zonal output signal of the piece-wise linear limiter. However, the performance analysis and curves are still valid for the types of soft limiters whose first zonal characteristic is described by eq. (2) of the paper.
