Method of using orthogonal or near orthogonal codes in the reverse link and system of wireless communications

摘要

Method of using orthogonal or near orthogonal codes in the reverse link and system of wireless communications. A technique for allowing a first and second group of users to share access to a communication channel such as a wireless radio channel is disclosed.The first group of users can be a group of users such as those that use legacy equipment digital CDMA cellular telephone based on the standard is - 95. The second group of users can be a group of net navigators for their transmissions using one of multiple formats.The first group of users can share one modulation structure such as, on a reverse link, using displacement of a single phase pseudo randu00f3mico noise code (PN). The second group of users can share another modulation structure, but in a way that is consistent and compatible with the users of the first group.Specifically, the users of the second group may all use the same code PN and phase shift of the code. Each channel used by the second user group can be identified only by a unique orthogonal code corresponding.
