Title: Inverse of a Special Matrix and Application,
Abstract: The matrix inversion is an interesting topic in algebra mathematics. However,
to determine an inverse matrix from a given matrix is required many computation
tools and time resource if the size of matrix is huge. In this paper, we have
shown an inverse closed form for an interesting matrix which has much
applications in communication system. Base on this inverse closed form, the
channel capacity closed form of a communication system can be determined via
the error rate parameter alpha
