Adaptive OFDM Techniques for Wireless ATM and UMTS Systems: Blind Modem Mode Detection and Turbo Coding
Sub-band adaptive OFDM modems are proposed and their performance is investigated using blind modem mode detection and turbo coding. Virtually error-free modem mode detection is achieved over Gaussian channels for Signal-to-Noise Ratios (SNR) in excess of about lOdB upon using one of four randem modes, namely 0, 1, 2 and 4 bits /symbol in each of the 16 subbands employed. The system can be configured for maintaining arbitrary target BERs, including virtually error-free communications, when adjusting the target number of bits / symbol transmitted.

Abstract

Sub-band adaptive OFDM modems are proposed and their performance is investigated using blind modem mode detection and turbo coding. Virtually error-free modem mode detection is achieved over Gaussian channels for Signal-to-Noise Ratios (SNR) in excess of about lOdB upon using one of four randem modes, namely 0, 1, 2 and 4 bits /symbol in each of the 16 subbands employed. The system can be configured for maintaining arbitrary target BERs, including virtually error-free communications, when adjusting the target number of bits / symbol transmitted.
