There is a need for echo cancelers for echo paths with long impulse responses (greater than or equal to 64 ms).
Optical transmission employing doubly periodic dispersion maps at 10 and 40 Gbit/s data rates is reported.
We consider networks of processors where each processor either has one inlink and one outlink, or two inlinks and two outlinks.
The capacity of wireless downlink communication to mobile receivers in a dense urban environment is limited primarily by co-channel interference.
In this paper system level simulation results from the performance evaluation of applicable downlink beamforming concepts for UMTS are presented.
This article gives a comparison of beamforming concepts.
Range extension by means of downlink beamforming in a wireless local area network (WLAN) orthogonal frequency-division multiplexing (OFDM) system is addressed.
Range extension by means of downlink beamforming in a wireless local area network (WLAN) orthogonal frequency-division multiplexing (OFDM) system is addressed.
A downlink beamforming for wireless local area network (WLAN)- type orthogonal frequency-division multiplexing (OFDM) system is addressed, where an access point is equipped with multiple antennas
Communication through multiple base station antennas with downlink time division multiplexing, rate control and scheduling is considered for high-speed packet data delivery.
