Abstract

In this paper, a scalable and real-time decision-based carrier tracking for software defined radio (SDR) for M-ary QAM modulation has been proposed and tested in real-time using the universal software radio peripheral (USRP)-2922. The proposed system provides real-time decision-based carrier tracking for improved efficiency and performance. The real-time transfer of data has been done using the USRP-2922 hardware using the M-ary QAM modulation scheme for data transmission. The novelty of the proposed system is that one can transfer random data (binary bits), text or an image which can be encoded using the desired forward error correction codes (FEC) namely the convolution coding/Viterbi soft decision decoding and the turbo coding/decoding. The proposed novel SDR transceiver system with real-time decision-based carrier tracking shows an improved performance for different parameters such as the bit error rate (BER) and signal to noise ratio (Eb/No).

基于M-ARY QAM调制的软件无线电实时决策载波跟踪

本文提出了一种可扩展的、基于实时决策的M-ary QAM调制软件无线电(SDR)载波跟踪方法，并利用通用软件无线电外设(USRP)-2922进行了实时测试。该系统提供基于决策的实时载波跟踪，以提高效率和性能。使用USRP-2922硬件，采用M-ary QAM调制方案进行数据传输，实现了数据的实时传输。该系统的新颖之处在于，人们可以传输随机数据(二进制位)、文本或图像，这些数据可以使用期望的前向纠错码(FEC)进行编码，即卷积编码/维特比软判决解码和涡轮编码/解码。基于实时决策载波跟踪的SDR收发器系统在不同的误码率(BER)和信噪比(Eb/No)等参数下都有较好的性能。
