Abstract

An LDPC-coded frequency hopping OFDMA system is proposed for the uplink of the cellular systems, where the frequency hopping is based on a resource block (RB) for coherent demodulation. For the system, two different RB types are considered either for better intercell interference averaging capability or for better channel estimation performance. A turbo receiver with iterative channel estimation and decoding is also proposed to provide better channel estimation performance without boosting the pilot power. The performance is evaluated both in single- and multi-cell environments to investigate the effect of the interference on the overall system performance.
