LOW CORRELATION/ ZERO CORRELATION SPREAD SPECTRUM CODE SETS CODING AND THE METHOD OF ITS APPLICATION

摘要

A coding of low correlation/ zero correlation spread spectrum code sets and method of its application, which has NK spread spectrum codes altogether, said NK spread spectrum codes are grouped into N code sets, and each set comprises K spread spectrum codes; wherein said group satisfies following conditions: there are low correlation/ zero correlation characteristics among N grouped code sets. Said method of applying low correlation/ zero correlation spread spectrum code sets can effectively eliminate interference from adjacent cell and adjacent sector, and reduce ACI significantly. Thus the capacity of the system can be improved.
