We study physical layer aspects of IEEE 802.15.4, especially focusing on the power spectrum and theoretical performance analysis of optimal receivers. We present the first formal analysis of the power spectrum of IEEE 802.15.4. We find that the power spectrum is similar to the MSK signal modulated by a 2 MHz chip sequence. Next, we analyze the error(More)
All pole lattice fi l te rs are used in a variety of signal processing applications that is speech processing, adaptive filters and various other applications. The implementation of lattice f i l t e r requires more clock period hence low speed. There are various transformation technique pr es ent for design of high-speed or low-area or lowpower(More)
