Frequency Domain Equalization for Single and Multiuser Generalized Spatial Modulation Systems in Time Dispersive Channels

Abstract: In this letter, a low-complexity iterative detector with frequency domain equalization is proposed for generalized spatial modulation (GSM) aided single carrier (SC) transmissions operating in frequency selective channels. The detector comprises three main separate tasks namely, multiple-input multiple-output (MIMO) equalization, active antenna detection and symbol wise demodulation. This approach makes the detector suitable for a broad range of MIMO configurations, which includes single-user and multiuser scenarios, as well as arbitrary signal constellations. Simulation results show that the receiver can cope with the intersymbol interference induced by severe time dispersive channels and operate in difficult underdetermined scenarios where the total number of transmitter antennas is substantially larger than the number of receiver antennas.

The electronic apparatus comprises an interface port for connecting to the connection part, a processing module for receiving the first signal, and a power unit for providing power to the antenna apparatus by the interface port.

Antenna Splitting Method in Active Antenna System and Controller

Abstract: The present invention relates to an antenna splitting method in an active antenna system and a controller, where the method includes: when load of an active antenna system AAS cell is greater than or equal to a load threshold, if a cell in an optimized area is not overloaded, load of a first cell is less than the load of the AAS cell, and load of a second cell is less than the load of the AAS cell, acquiring a first antenna parameter combination corresponding to a maximum capacity of the optimized area; and splitting an AAS antenna according to the first antenna parameter combination. The antenna splitting method in an active antenna system and the controller according to embodiments of the present invention can effectively reduce the load of a heavily loaded AAS cell, and effectively increase a capacity of the optimized area.
