Improvements of IEEE 802.15.4a for non-coherent energy detection receiver

Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Moreover, it is able to offer accurate localization in the range of few centimeters. Regarding these qualities, it is desirable to design an IR-UWB transceiver which consumes as little power as possible when it is applied for battery driven wireless sensors. For this reason an IRUWB transceiver based on the standard IEEE.802.15.4a was investigated in this paper with particular emphasis on energy efficiency, data rate, latency, synchronization and preamble detection. This paper demonstrates the optimization potential of the official standard IEEE.802.15.4a. Different methods for optimization are investigated and combined.
