    • A method for controlling transmit power of a preamble sequence by a Subscriber Station in an Orthogonal Frequency Division Multiple Access communication system, the system dividing an entire frequency band into a plurality of sub-carrier bands, transmitting an preamble sequence for an Adaptive Antenna System, transmitting a data symbol through remaining sub-carrier bands excluding the sub-carrier bands. The method includes determining the transmit power used for transmitting the data symbol; and determining the transmit power used for transmitting the preamble sequence to be identical to a preset threshold transmit power when the transmit power of the data symbol is smaller than the threshold transmit power, and determining the transmit power used for transmitting the preamble sequence to be identical to the transmit power of the data symbol when the transmit power of the data symbol exceeds the threshold transmit power.
    • 一种用于在正交频分多址通信系统中由用户站控制前导序列的发射功率的方法,该系统将整个频带划分为多个子载波频带,发送用于自适应天线系统的前导码序列, 通过除子载波频带之外的剩余子载波频带发送数据符号。 该方法包括确定用于发送数据符号的发射功率; 以及当所述数据符号的发射功率小于所述阈值发射功率时,确定用于发送所述前置码序列的所述发射功率与预设的阈值发射功率相同,以及确定用于将所述前同步码序列发送相同的所述发射功率 当数据符号的发送功率超过阈值发送功率时,发送到数据符号的发送功率。
