Abstract

Abstract:

Combining vertical bell laboratories layered space time(VBLAST) and multi code code division multiple access(CDMA) is an effective way to improve data speed, a good communication character can be obtained based on spreading codes with zero correlation window. The capacity formulas are proposed based on the study of the capacity of VBLASTCDMA system under loose synchronization (LS) code and Walsh code respectively under frequency selective and correlative channels. It shows that the capacity of VBLASTCDMA based on LS code is higher than that based on Walsh code.

Key words: correlated channels, vertical bell laboratories layered space time, multi-code code division multiple access, capacity
