Title:
アクセスバースト検出器の相関器プール
Document Type and Number:
Japanese Patent JP2005528023
Kind Code:
A
Abstract:
A Node-B/base station has an access burst detector. The access burst detector comprises at least one antenna (28 1 -28 M ) for receiving signals from users and a pool of reconfigurable correlators, implemented in ASIC. Each correlator (36 1 -36 O ) correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller (30) selectively couples any output of the at least one antenna to an input of any of the correlators. A code controller (32) provides to an input of each correlator an access burst code. The code controller controls the inputted code phase of each controller. A sorter/post processor (38) sorts output energy levels of the correlators.
