This paper presents a new method for timing synchronization in mobile transceivers utilizing direct sequence spread spectrum signaling (DSSS) for target localization. Traditional methods of timing synchronization for DSSS produce variable latency that depends on channel characteristics and configuration. This latency produces bias in range measurements which causes errors in position estimation. Our...
In this paper, we apply results from multi-user information theory to study the limits of information capacity and collision resolution for SAW RFID tags. In particular, we derive bounds on the achievable data rate per tag as a function of fundamental parameters such as tag time-bandwidth product, tag signal-to-noise ratio (SNR), and number of tags in the environment. We also discuss the implications...
