Abstract :
The architecture and implementation of a time-division multiple-access digital portable communication system using short bursts are considered. An efficient and robust TDMA frame structure that requires very low overhead for burst demodulation and synchronization while being robust against fading and carrier frequency offset is described. Based on this frame structure, an experimental radio link was implemented by using a hardware architecture that is suitable for digital signal processing and very large-scale integration implementation. Implementation of demodulation, synchronization, error detection, and fading recovery using combined software and off-the-shelf hardware is described, followed by a summary of the performance results.<>
