SIR-based preamble detection in wideband cdma systems

  • 摘要: 該文研究多徑衰落信道條件下,基于SIR的前導(dǎo)檢測。以WCDMA中隨機(jī)接入信道(RACH)和公共分組信道(CPCH)為例,設(shè)計了兩天線接收機(jī)結(jié)構(gòu),推導(dǎo)了前導(dǎo)檢測性能表達(dá)式。通過理論分析和計算機(jī)仿真對3種兩天線信號的利用方式進(jìn)行了比較。
    Abstract: SIR-based preamble detection is investigated under multipath fading condition. Two-antenna receiver is designed for the random access channel and common packet channel in WCDMA uplink. The preamble detection performance is derived and closed-form expressions are given. Three utilization methods of antennas signals are compared by theoretical analysis and computer simulations.
