Ternary-Sequence-Based-OFDM-Frame-Synchro-in-WIFI
In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame
synchronization is an essential procedure for normal operation of
the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of
orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.

SIM卡为表示能够执行proactive command且支持SAT，它必须在文件EFphaseTKG EFsst中有相关数据。 Phase文件指的是SIM卡所支持的GSM标准的级数，值为3则指SIM卡支持GSM phase 2和设置下传功能（profile download)。SST文件包含支持哪些GSM性能的准确信息。(SIM card that can support the implementation of proactive command and the SAT, it must file EFphaseTKG EFsst have relevant data. Phase document refers to the SIM card supports the GSM standard series, a value of 3 means the SIM card supports the GSM phase 2 and settings transfer function (profile download). SST file which contains support for GSM performance of accurate information.)

SIGNAL DETECTION FOR SPECTRUM SENSING
Spectrum sensing is a critical functionality in cognitive radio communications as it must be performed before allowing unlicensed users to access a vacant licensed band. Energy detector is also known as radiometer and it is most common method of spectrum sensing because of its low computational and implementation complexities. The coherent detector, also referred to as a matched filter, can improve detection performance if the primary transmitted signal, s, is deterministic and known a priori.
