[Software Engineering] EFFICIENT-DECODING-OF-WATERMARKING DL : 0: 在这项工作中，我们对待这个问题的恢复正确的消息，如果额外的位（假报警）已加入的消息体中，在随机的位置。这的情况是常见的一些是与选择性嵌入水印系统典型的当人类视觉系统（或录音）注册成立，以提高质量水印系统。我们提出一个有效的解码方案使用一些修改的“维特比算法的代码。添加额外的状态表示可能的误报率和一个新的扩展算法的改进网格提出图。仿真结果表明，我们的算法在高效率的检测随机的误报率很高。-In this work, we treat the problem of recovering the correct message if extra bits (false alarms) are added to the body of the message at random locations. This situation is common for some watermarking systems with selective embedding which is typical when the human visual (or audio) system is incorporated to enhance the quality of the watermarking system. We propose an efficient decoding scheme for convolutional codes using some modifications of‘ the Viterbi algorithm. Extra states are added to represent the possible false alarms and a new expansion algorithm of the modified trellis diagram is proposed. The simulation results show the high efficiency of our algorithm in detecting random false alarms with high rates.

[matlab] OFDM_basic DL : 0: 多输人多输出(MIMO)技术是第三代和未来移动通信与个人通信系统实现高数据速率，提高传输质量的重要途径[1 ]。目前MIMO系统中使用的发射方案主要包括：①贝尔分层空时结构BI STA(Bell Layered Space Time Architecture)[。；②正交空时分组码OSTBC(Orthogonal Space Time Block Coding) ；⑧空时格型编码STTC(Space Time Trellis Coding) 。-Motivated by the need for high throughput sphere decoding formultipleinput- multiple-output (MIMO) communication systems, we propose a parallel depth-first sphere decoding (PDSD) algorithm that provides the advantages of both parallel processing and rapid search space reduction. The PDSD algorithm is designed for efficient implementation on programmable multi-processor platforms. We investigate the trade-off between the throughput and computation overhead when the number of processing elements is 2, 4 and 8, for a 4× 4 16-QAM system across a wide range of SNR conditions. Through simulation, we show that PDSD can offer significant throughput improvement without incurring substantial computation overhead by selecting the appropriate number of processing elements according to specific SNR conditions.

[matlab] vitsimdemo DL : 1: 采用卷积编码与维特比译码对通信过程进行了仿真，展示了卷积码的差错校正容量，调制方式采用QPSK-This demo shows how to use a convolutional encoder and decoder in a simulation of a communications link. It also shows the error correcting capability of convolutional codes. This demonstrates the convolutional trellis generator, POLY2TRELLIS, encoder, CONVENC, and decoder, VITDEC. It also demonstrates the use of other functions (e.g. INTDUMP, RECTPULSE, BITERR, BERCODING, RANDSRC, and AWGN) and objects (MODEM.PSKMOD and MODEM.PSKDEMOD). Many of these functions are described in greater detail in the "Phase Shift Keying Simulation" demo. Finally, this demo displays empirical performance curves for QPSK with Gray coding using data generated by the example, VITSIMEXAMPLE.
