Abstract
A method and apparatus for performing Joint Randomness Not Shared by Others (JRNSO) is disclosed. In one embodiment, JRNSO is determined in Frequency Division Duplex (FDD) using a baseband signal loop back and private pilots. In another embodiment, JRNSO is determined in Time Division Duplex (TDD) using a baseband signal loop back and combinations of private pilots, private gain functions and Kalman filtering directional processing. In one example, the FDD and TDD JRSNO embodiments are performed in Single-Input-Single-Output (SISO) and Single-Input-Multiple-Output (SIMO) communications. In other examples, the FDD and TDD embodiments are performed in Multiple-Input-Multiple-Output (MIMO) and Multiple-Input-Single-Output (MISO) communications. JRNSO is determined by reducing MIMO and MISO communications to SISO or SIMO communications. JRNSO is also determined using determinants of MIMO channel products. Channel restrictions are removed by exploiting symmetric properties of matrix products.
