Abstract
Official abstract text for this publication.
One out of sixteen preamble signatures is selected. A code is produced based on the selected preamble signature. The produced code is phase rotated to produce a processed preamble signature signal. The processed preamble signature signal is used in processing the CDMA RACH signal and the CDMA RACH signal is used to access a CDMA system.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for use in processing a preamble of a random access channel (RACH) signal, the method comprising: selecting one preamble signature out of a plurality of preamble signatures; producing a code based on the selected preamble signature; and phase rotating the produced code to produce a processed preamble signature signal, the processed preamble signature signal used in processing the RACH signal. 2. The method of claim 1 , w…
