We adopt a general Gaussian function shifted in time by 0.5 ns and truncated at /spl plusmn/0.25 ns and its derivatives for a UWB waveform and its shaping, and employ a TH-SS (time hopping spread spectrum) technique. Three types of typical data modulation schemes - PPM, BPSK and BPAM - are used. It is important to choose an appropriate modulation scheme that has a smooth spectrum reducing the spectral lines to result in maximum power efficiency because of possible limits on the UWB transmit power emission level for wireless network applications. The adopted UWB systems are designed to consume extremely low AC power. We describe some UWB features which attract many battery operated mobile applications such as WPANs. The UWB signal can be seen as random noise to the IEEE 802.11 WLAN signal, whose bandwidth is 22 MHz. The bandwidth of the WLAN interference signal is only a small fraction of the UWB signal bandwidth, which means that the UWB system has robust noise performance. The transmitted average power of the UWB signal is extremely low. Therefore, the WLAN and WPAN systems can coexist in the same 2.4 GHz ISM band.","PeriodicalId":6305,"journal":{"name":"2003 IEEE Topical Conference on Wireless Communication Technology","volume":"9 1","pages":"459-460"},"PeriodicalIF":0.0,"publicationDate":"2003-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86220076","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}

Recently, many spatial signal processing technologies based on plural antennas and signal processing has been studied. It is well known that the technologies, i.e., adaptive array, space division multiple access (SDMA), and multi-input multi-output (MIMO) provide increasing communication quality, spectrum efficiency, and throughput. However, the technologies are not yet almost utilized for the actual product. In order to introduce the spatial signal processing technologies to real commercial products, we have studied and developed them. We consider that a mobile terminal has a limitation of performance of a processor and power consumption. Therefore, we have studied the technologies that do not require heavy performance for a mobile terminal. In this paper, we present results of our research and development: the adaptive array PHS base station, SDMA PHS test bed, MIMO PHS test bed, and adaptive array WLAN test bed. We have carried out field tests for the AA PHS BS in Tokyo. The results of the field test show that the AA PHS BS increases the system traffic by about 11% and reduces interference level as compared with the existing PHS BS. Results of the field test for the SDMA PHS test bed indicate that the SDMA test bed improves the traffic by about 2.4 to 2.7 times, and can coexist with the existing PHS BS. Results of the indoor test for the MIMO PHS test bed indicate that the test bed establishes two stable paths if the MIMO BS antenna distance is larger than 1.0 /spl lambda/ and the MIMO terminal antenna distance is larger than 0.3 /spl lambda/. We also have developed an adaptive array test bed for the wireless LAN, i.e., IEEE 802.11b. Results of the field test show that the AA-WLAN test bed expands communication distance by 1.9 times, and increases average throughput.","PeriodicalId":6305,"journal":{"name":"2003 IEEE Topical Conference on Wireless Communication Technology","volume":"68 1","pages":"180-"},"PeriodicalIF":0.0,"publicationDate":"2003-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82345274","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}
