    • The present invention differs from the prior art in that the present invention provides one or a network of passive or active radio frequency identification (RFID) transceivers and antenna elements in different numbers, in various network sizes, in different configurations and on various substrates. The RFID transceiver can be co-located with standard semiconductor devices, for cost-effective circuit design and non-destructive fabrication test and analysis of integrated circuits and printed circuit boards after fabrication, and to locate, track and identify the integrated circuit, printed circuit boards and products in which they are implemented. The RFID transceivers can be coupled to substrates containing matter in gas, liquid, or solid form, such as medical devices like breast implants, for effective monitoring of the substrates to ensure that the substrate is in an unaltered state and the matter is still contained securely within. The RFID transceivers can be coupled to secure tapes of various lengths and widths and mesh bags or sheets of various sizes and they can be applied at the carton-level using them to locate, track and identify the integrated circuit, printed circuit boards and products in which they are implemented and/or the cartons in which they were placed.

    • The synchronization technique invention uses inherent characteristics of the frequency domain representation of the data symbols. By computing a differential-in-frequency function across a large number of OFDM tones, robust estimates of time and frequency offset can be easily obtained. The technique also allows the system designer to directly trade performance in the presence of channel impairments against signal processing complexity. Analysis and simulation have shown good performance in the presence of noise and channel delay dispersion, impairments that are the harshest in a wireless environment. Prior techniques for OFDM synchronization have focussed on the time domain representation of the signal. Those that have recognized the translation of time and frequency offset to the frequency domain have not considered the systematic modification of the signal by the offsets.
    • 同步技术发明使用数据符号的频域表示的固有特性。 通过计算大量OFDM音调的频率差分函数,可以容易地获得时间和频率偏移的鲁棒估计。 该技术还允许系统设计者在存在针对信号处理复杂性的信道损伤的情况下直接交换性能。 在存在噪声和信道延迟色散的情况下,分析和仿真显示出良好的性能,这在无线环境中是最严重的。 用于OFDM同步的现有技术集中在信号的时域表示上。 已经认识到对频域的时间和频率偏移的转换的那些没有考虑通过偏移对信号的系统修改。
