These activities are carried out mainly by echolocation, i.e. by transmitting pulses at ultrasound frequencies and processing the echoes from targets. Because they have relied on high level performance for survival, as a consequence of natural selection, it is believed that they have evolved in order to optimise these capabilities. Echolocation calls are very sophisticated, diverse, and commonly composed of a number of harmonic components. If evolution has resulted in multi-harmonic waveforms there might be advantages deriving by doing so. In this paper we simulate multi-harmonics waveforms and exploit advantages or disadvantages by a range analysis of their ambiguity functions. Results are discussed in relation to the radar and sonar case.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129235966","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}

With increasing numbers of radio frequency sensors and communications systems, battlefield scenarios have become more complex and continuously redefined. Our challenge will be to effectively use this technology to enhance overall performance of advanced radar systems operating within available spectrum in these battlefield environments. Technologies essential to this goal include cognition and knowledge based systems for waveform generation timing and control, and intelligent radar signal/data processing for detection, parameter estimation and track processing. Cognition is defined as the act or process of knowing, including both awareness and judgment. Awareness of the dynamically changing spectral environment and judgment for the selection of optimal waveform parameters and sensor placement will enable dramatically improved performance for target surveillance/reconnaissance in addition to enhanced interference mitigation. A confluence of factors and technologies now makes waveform diverse knowledge based systems a logical and affordable alternative to classically designed radars.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125907490","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}

We show that this adaptive mechanism outperforms MIMO radar systems that transmit fixed equal energy across all the antennas.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114506506","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}

Contrarily, the full-duplex protocol offers higher capacity by letting the relay transmit and receive simultaneously in the same frequency band. In this work, we conduct a bit error rate (BER) analysis of a full-duplex relaying scheme that employs binary phase shift keying (BPSK) and a single decode-and-forward relay. The derived closed-form expression gives insight into the BER performance, demostrating inferior performance as compared to the HD protocol, as well as zero diversity order due to the existence of self-interference at the relay and destination.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123478601","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}

Multi-frequency radar techniques are then applied for range estimation of each path.

However, the S-K scheme and related techniques rely on the presence of a noiseless feedback channel which is not practical. In this paper, we look at introducing the notion of quantization into linear feedback coding. To accomplish this, we look at adapting a recent linear feedback scheme [3] built on a noisy feedback channel to a system where the feedback is now quantized to be in the form of a binary message. This form of feedback gives insight into the relationship between bits of feedback and received signal-to-noise ratio given a blocklength, and, also, how the precision of feedback relates to average transmit power.","PeriodicalId":112343,"journal":{"name":"2010 International Waveform Diversity and Design Conference","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132316632","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}
