The transform domain communication system (TDCS) is one spectrum agile transceiver technology in the cognitive radio (CR) contexts. It gives an effective and available way to resolve current spectrum resource scarcity. This paper briefly introduces the basic theory of the TDCS transceiver. The primary goal of this paper is to give a detailed description of the channel estimation (CE) in TDCS receiver...
Node self-positioning is a fundamental and crucial issue for sensor network operation, management and applications. In this paper, an efficient location method is proposed based on received signal strength information (RSSI). We first utilize the known-location nodes (anchor nodes) to locate the unknown-location nodes in a single-hop range, and the estimated nodes are regarded as new anchor nodes...
