摘要 分析了802.11a无线局域网(WLAN)OFDM基带接收系统中频率同步和信道估计算法的运算特点。针对实际算法的特点,设计了一个面向应用的专用DSP处理器(ASP),利用ASP可以以软件方式实现802.11a前导序列的接收。经实际流片验证表明,该设计可以实现11a前导序列接收的各种基带处理运算,具有高度的灵活性和较小的芯片面积。 This paper analyzes the calculation cost and characteristics of 802.11 a preamble receiving. Realization of these algorithms using SDR, which is based on an application specific DSP and S/W codesign, is introduced. An effectively DSP processor architecture is designed. The test results show this design is able to implement 11a baseband process effectively and flexibly.
