The Error of TD-SCDMA and Its Correction Schema
The paper proves the unusability of smart antenna(SA) which is defined in the TD-SCDMA standard,and so theTD-SCDMA standard should be improved.A reform schemawill be given in this paper,which uses CDMA/TDMArespectively in the uplink/downlink channel.In this schema,theSA can still be used in downlink channel.It will give a new lifeto TD-SCDMA standard.8PSK or 16QAM can be used in thedownlink channel,which has higher spectrum efficiency.Theywill transfer the surplus downlink power to the spectrumefficiency.The improved TD-SCDMA standard will meet theneeds of the mobile intemet.
