Abstract :
The Wind-Flex project has developed a wireless indoor high bit rate OFDM modem, operating at 17 GHz. This modem is a packet-radio based system with a highly dynamic bit-rate range between 64 Kbit/s and 100 Mbit/s. Simulations for implementation have been done to evaluate the performance of the Wind-Flex modem using a concatenated coding scheme in combination with a TDMA-based block repetition mechanism. A simple ARQ-like delay reduction procedure is also presented. We show that TDMA-based repetition can significantly enhance the performance of the packet-oriented concatenated codec by trading off data rate for robustness. This does not lead to increased complexity in the modem implementation
