摘要

重点研究了支持语音和数据业务的FDMA/CDMA混合系统的Erlang容量评估;独立载波信道分配(ICCA)方案和联合载波信道分配(CCCA)方案。结果表明，随着FDMA/CDMA混合载波数量的增加，CCCA方案的Erlang容量有了较大的提高。在载波数量固定的情况下，CCCA的Erlang容量与具有小信道元的ICCA的Erlang容量基本相同。但CCCA的性能优于ICCA, ce值也有所增加。

Improved Erlang capacity of combined carrier channel assignment for hybrid FDMA/CDMA systems supporting voice and data services

The authors focus on the evaluation of the Erlang capacity for hybrid FDMA/CDMA systems supporting voice and data services with two channel allocation schemes; the independent carrier channel assignment (ICCA) scheme and the combined carrier channel assignment (CCCA) scheme. As a result, the CCCA scheme shows considerable Erlang capacity improvement with an increase of carriers of hybrid FDMA/CDMA. For a fixed number of carriers, the Erlang capacity of CCCA is almost the same as that of ICCA with small channel elements (CEs). However, CCCA outperforms ICCA with an increase of CEs.
