In this paper, we propose a quantized predictive precoding scheme for spatial multiplexing multiple- input multiple-output (MIMO) systems with delayed feedback. A geodesic transmit subspace prediction algorithm is designed to predict the transmit subspace for the forthcoming transmission at the receiver. An infrequently updated codebook for transmit subspace quantization is developed to improve the...
To distinguish between a pair of transition faults, we need to find a test vector pair (LOC or LOS type)that produces different output responses for the two faults. By adding a few logic gates and one modeling flip-flop to the circuit under test (CUT), we create a diagnostic ATPG model usable by a conventional single stuck-at fault test pattern generator. Given a transition fault pair, this ATPG model...
Polarization filtering attracts extensive attention for its special property in solving problems which are unable to deal with in temporal or frequency domain. Conventional polarization filter can suppress interferences by seeking for the orthogonal vector of the interferences while it will inevitably bring in distortion to the target signal in its amplitude and phase; Null phase-shifting polarization...
