LTE-Advanced extends the capabilities originally developed in LTE within the 3GPP. Carrier aggregationis the most significant, albeit complex, improvement provided by LTE-Advanced. Bandwidths from various portions of the spectrum are logically concatenated resulting in a virtual block of a much larger band, enabling increased data throughput. Additionally, enhancements to MIMO antenna techniques in...
The existing cooperative spatial multiplexing (CSM) schemes for MIMO-CDMA network have four vital problems to hinder CSM's application: exact synchronization among the mobile stations(MSs) and base station (BS), spatial channels' estimation for MSs, space-time coding and decoding for BS and MSs, the implementation complexity of BS and MSs. To solve the problems, a simplified cooperative spatial multiplexing...
