Abstract :
In the early 1990s investigations towards an air interface for UMTS and IMT-2000 started at the Research Group for RF Communications. The result is the JD-CDMA air interface, which formed the basis of the UMTS air interface mode TD-CDMA. JD-CDMA uses a combination of the multiple access schemes FDMA, TDMA and CDMA, in which signal separation is performed by joint detection (JD). To prove the performance and the feasibility of JD-CDMA a hardware demonstrator was build by the Research Group for RF Communications and Siemens AG. The JD-CDMA implementation for the demonstrator adopts the philosophy of the de facto world standard GSM to an extent as large as possible. The paper investigates which extensions of existing GSM handoff protocols are necessary to support a multiple cell JD-CDMA hardware demonstrator
