Title:
ワイヤレス通信システムにおいて直交送信ダイバーシチおよび適応型アレイ手法を組み合わせる方法およびシステム
Document Type and Number:
Japanese Patent JP4541552
Kind Code:
B2
Abstract:
A receiver for use in a wireless communication system, wherein the wireless communication system includes a transmitter that spreads data with multiple spreading codes. The receiver includes a plurality of despreaders for despreading with multiple despreading codes corresponding to the multiple spreading codes in the transmitter. A plurality of demodulators demodulate outputs of the plurality of despreaders, and a demultiplexer demultiplexes the outputs of the plurality of demodulators. A decoder decodes the output of the multiplexer to produce received traffic channel data. The receiver uses a pilot selector for selecting, in response to a control signal, a reference signal for use in the plurality of demodulators. A mode detector that produces the control signal is responsive to the transmitter transmitting in an orthogonal transmit diversity mode or an adaptive array mode.
