| Shrnutí: | This study presents a baseband communication architecture in compliance with IEEE 802.15.4 physical layer specifications for body area network systems. The proposed architecture uses preambles for a correlation operation to detect the front end of symbols and then calculates the influence of a channel effect, for example, a carrier frequency offset (CFO). Using a cross-correlation and auto-correlation architecture to synchronize receivers, the data subject to the carrier frequency can be compensated with a coordinate rotation digital computer (CORDIC) structure. This study includes a system simulation for the purpose of signal compensation in both the transmitting and receiving ends. Results show that the proposed design correctly detects the CFO bias in radians, with a detection error less than 0.1%, indicating that the CFO is compensated. |
