METHOD FOR CALCULATING SECURITY CAPACITY OF GAUSSIAN MIMO WIRETAP CHANNEL

摘要

PURPOSE: A method for calculating stability capacity of a MIMO Gaussian tapping channel using a channel gain parameter of a SIMO channel is provided to divide a MIMO channel into SIMO channels and calculate a channel gain parameter of the SIMO channels, thereby directly calculating safety capacity of the MIMO Gaussian channel. CONSTITUTION: A MIMO(Multi-Input Multi-Output) Gaussian channel is divided into a plurality of SIMO(Single Input Multiple Output) channels(S1). The SIMO channels are transformed into each scalar channel(S3). A safety capacity of the SIMO channels is calculated by using main communication channel parameter of the scalar channel and a wiretap communication channel parameter(S7). A safety capacity of the MIMO Gaussian channel adds safety capacity of the SIMO channels and is calculated(S9).
