We describe a secure communication scheme that uses the random fluctuation of the natural environment of communication channels. Only the transmitter and the receiver share the communication channel characteristics. From reciprocity between a transmitter and a receiver, it is possible for them to share one-time information of their fluctuating channel. This(More)
We first consider the problem of decoding a signal from a memoryless SIMO (single-input/multiple-output) channel subject to block-wise stationary cochannel interference (CCI). We employ an iterative expectation-maximization method, arriving at an algorithm which alternately performs a beamforming via a sample matrix inversion and a maximum-likelihood(More)
