The general space-time coding/modulation structure in [1] is considered. Several design issues are investigated for this structure. The layered space-time architecture in [2] is revisited as a special case of the general structure. It is also used to demonstrate the design and complexity tradeoffs of the system. Through intuitive and analytical explanations, as well as simulations, the design considerations for these space-time transmission structures and their contributions to the performance will be shown.Grouped space-time (GST) transmission; Signal space separation; Space-time coded multi-antenna systems; Space-time transmission structures; Antennas; Computer simulation; Data communication systems; Information technology; Modulation; Signal processing; Wireless telecommunication systemsjournal article10.1155/S11108657020008352-s2.0-0036590628WOS:000176893300004
