To estimate multiple-input multiple-output (MIMO) channels, invariable step-size normalized least mean square (ISSNLMS) algorithm was applied to adaptive channel estimation (ACE). Since the MIMO channel is often described by sparse channel model due to broadband signal transmission, such sparsity can be exploited by adaptive sparse channel estimation (ASCE) methods using sparse ISS-NLMS algorithms...
In WCDMA system, rate assignment algorithm on the downlink for the data transmission is proposed. The optimization goal of the resource allocation strategy is choosing appropriate utility function. The utility function reflects a flexible tradeoff between total system throughput and fairness. The power is distributed through the control module and the scheduling module. The simulations show the performance...
Employing an optical pulse shaper with 1.6 GHz/pixel resolution, we experimentally demonstrate optical compensation of all-order polarization mode dispersion with >40 ps mean differential group delay in a 10 Gbit/s×2 Pol-Mux system.
We experimentally demonstrate optical compensation of all-order polarization mode dispersion with >50 ps mean differential group delay in a 10 Gbit/s??4 OTDM system using an optical pulse shaper with 1.6 GHz/pixel resolution.
The vector sensor can be competent for measuring the information of pressure and velocity synchronously and independently. Acoustic multi user communication system based on single vector sensor, which can be used to separate several source from each other by calculating the inverse channel matrix, can be equivalent to MIMO system. Theoretical calculation and simulation have shown that the algorithm...
In order to ensure real time running of adaptive receivers on multi-path fading channels in DS-CDMA systems, a new scheme is considered using the non-blind algorithm by jointing parallel interference cancellation (PIC) and adaptive minimum mean-squared error (MMSE) receivers, the proposed scheme has a relatively lower computational complexity compare to conventional methods. Simulations show that...
