However, in the progress of ADC, if the received signal power exceeds the operation range of receiver, the system performance is degraded drastically. In this paper, we propose an Automatic Gain Control (AGC) design scheme for IEEE 802.11a based on the correlator and threshold detector. The proposed scheme estimates the received signal power using the correlation value with the Short Training Sequence (STS) of preamble and transmits these parameters to the AGC for gain control of receiver. In addition, if the high power received signal that exceeds the operating range of ADC is received, proposed scheme can control the correlation output using the threshold detector and feedback loop. The proposed scheme has the large operating range more than 60 dB and can be performed by two short training sequences.","PeriodicalId":153613,"journal":{"name":"2012 International Conference on Control Engineering and Communication Technology","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134090452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to exactly estimate communication system performance, a channel simulator needs to simulate power amplifier nonlinearity. This paper proposes a novel adaptive simulator based on piecewise polynomial. Learning from the digital predistortion technique of power amplifier, the proposed method uses adaptive study structure. It adds a nonlinear preprocessing module before the radio power amplifier of channel simulator, and uses adaptive algorithm to make their cascading characteristics gradually approach to the simulated power amplifier nonlinearity. In order to solve the disadvantages in traditional polynomial and look-up table techniques, the proposed method uses multiple lower-odd-order polynomials to piecewise fit nonlinearity for improving simulation precision. And the look-up table is used to store polynomial coefficients for reducing the computational load. The simulation results indicate that the proposed method provides high simulation precision and fast convergence speed.","PeriodicalId":153613,"journal":{"name":"2012 International Conference on Control Engineering and Communication Technology","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124720073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resolution of the wideband phased array is higher than the narrow phased array. But the frequency band of the wideband phased array is wider. Traditional method can't compensate the wave path difference completely, which causes the beam broadening and the antenna gain decreasing. The phenomenon of \"\"\"\"aperture transition\"\"\"\" will occur in the case of large scan angle for wideband phased array, which causes the range resolution decreases. A method based on true time delay that compensates the wave path differences of all frequency components within the signal bandwidth is presented in this paper. The wideband linear frequency modulated signal is illustrated to realize true time delay of phased array and demonstrate the effectiveness of the proposed method by computer simulation. The result of computer simulation demonstrates that the wideband passive phased array based on true time delay has the same antenna gain and azimuth resolution with the narrow band phased array and improves the range resolution.","PeriodicalId":153613,"journal":{"name":"2012 International Conference on Control Engineering and Communication Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129357873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
