The Error of TD-SCDMA and It's Correction Schema

The paper proves the unusability of smart antenna (SA) which is defined in the TD-SCDMA standard, and so the TD-SCDMA standard should be improved. A reform schema will be given in this paper, which uses CDMA/TDMA respectively in the uplink/downlink channel. In this schema, the SA can still be used in downlink channel. It will give a new life to TD-SCDMA standard. 8 PSK or 16 QAM can be used in the downlink channel, which has higher spectrum efficiency. They will transfer the surplus downlink power to the spectrum efficiency. The improved TD-SCDMA standard will meet the needs of the mobile internet.
