    • PURPOSE: A continuous time type chaos signal generation circuit using a voltage control variable resistance is provided to indicate the state variable of a chaos equation by controlling a consequent operational point indicating a current-voltage curve characteristic of a non-linear negative-resistance. CONSTITUTION: A variable resistor(R) serially connects to the one side of an inductor-first capacitor circuit in a cutting node. A non-linear resistor is connected to the space between the other side of the variable resistor and the other side of the inductor-first capacitor circuit. A second capacitor(C2) is connected to the non-linear resistor in parallel. The variable resistor is implemented as a MOS transistor. The variable resistor includes a control transistor connected to the both ends of the variable resistor source and drain terminals.

    • 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).
