—In this paper, we propose the time-division multiplexing (TDM) based MIMO channel sounding technique using loosely synchronous (LS) codes for real time measurement of MIMO radio channel. Since LS codes have perfect auto-correlation and cross-correlation functions within certain vicinity of the zero shifts, the proposed technique can substantially reduce(More)
In order to reflect a realistic wireless channel as closely as possible, the channel model becomes very complicated and is thus prone to error when implemented as a channel simulator. However, there is no rigorous way of verifying the implementation of the channel simulator. We propose a novel verification methodology that aims at implementing a verified(More)
(RxACC), channel capacity and eigenvalues of HH * where H and (*) are channel frequency response matrix and conjugate transpose. Based on eigenvalue characteristics, we derive mean and variance of eigenvalue which are a function of the absolute value of TxACC, |TxACC|, the absolute value of RxACC, |RxACC|, and the number of Rx antennas, and then model(More)
