Antenna systems with common overhead for cdma base stations
TL;DR: In this article, a micro-timing offset between signals transmitted on adjacent pairs of pairs of beams is proposed to ensure that destructive cancellation substantially does not occur between the pair of beams.
Proceedings ArticleDOI
A novel spatial modulation using MIMO spatial multiplexing
TL;DR: A new Multiple-Input Multiple-Output (MIMO) transmission scheme that combines the generalised spatial modulation (GSM) with MIMO spatial multiplexing technique is proposed which is based on a zero forcing detector.
Journal ArticleDOI
Improved spatial modulation for high spectral efficiency
TL;DR: The simulations results show that the proposed scheme outperforms the optimal SM and V-BLAST (Vertical Bell Laboratories Layered space-time at high signal-to-noise ratio) in an uncorrelated Rayleigh fading channel.
Patent
Method and apparatus for increasing capacity for wireless data transmissions
TL;DR: In this article, a method and apparatus for transmitting wireless data to users which increases the wireless capacity for data transmissions within a sector served by a base station is disclosed, where the sector is subdivided into a plurality of beams, typically by means of beam forming antennas, and the user data to be transmitted is time division multiplexed by scheduling the data into timeslots for transmission via the beams.
Journal ArticleDOI
Improved Spatial Modulation for High Spectral Efficiency
TL;DR: In this article, a spatial modulation (SM) and spatial multiplexing (SM-SM) scheme was proposed to improve the spectral efficiency of MIMO transmission in Rayleigh fading channels.
