Design of an OFDMA baseband receiver for 3GPP long-term evolution

Abstract

In this paper, we propose a downlink OFDMA processor based on the 3GPP LTE. This processor supports scalable bandwidth for different OFDMA modes. A low-cost sampling rate conversion is employed to obtain different sampling rates for different bandwidths. Timing and frequency synchronization are then designed to recover the time and frequency mismatch… (More)
