Performance Analysis of Service Differentiation for IEEE 802.15.4 Slotted CSMA/CA
In this paper, we propose two mechanisms, differentiation by backoff exponent and differentiation by the size of contention window, for IEEE 802.15.4 sensor networks to provide mul...

Performance analysis on LDPC-Coded systems over quasi-static (MIMO) fading channels
In this paper, we derive closed form upper bounds on the error probability of low-density parity-check (LDPC) coded modulation schemes operating on quasi-static fading channels. Th...
