Title:
【発明の名称】CDMAシステムのキャパシティを増加させる時間オフセット技術
Document Type and Number:
Japanese Patent JP2002523963
Kind Code:
A
Abstract:
A method for limiting peak transmit power in a CDMA communication system by transmitting a first communication signal having a first high transmit power region, and transmitting a second communication signal having a second high transmit power region. A first and a second communication signal are time offset to prevent the first and second high transmit power regions from occurring simultaneously. Time shifting only a portion of the first and second communication signals is also taught. The first and second communication signals can also include respective first and second low transmit power regions. The time offset can be selected to align one of the first and second high transmit power regions with one of the first and second low transmit power regions. The total transmit power signal can be determined and the time offset can be selected to minimize a peak level of the total transmit power signal. The communication signals are separated into a plurality of portions and portions of the first and second communication signals are time offset to re-order the sequence of transmission of the plurality of portions.
