An efficient architecture for OFDM baseband receiver based on coordinate rotation digital computer (CORDIC) algorithm is proposed with channel state information (CSI). Two dual-mode CORDIC modules are designed for synchronization and equalization. A modified demapping method using CSI helps to provide sub-channel status, and therefore decreases packet error(More)
An efficient frame and symbol synchronization, and digital automatic gain control (AGC) for Orthogonal Frequency Division Multiplexing (OFDM) based wireless LAN (WLAN) defined in IEEE 802.11a had been proposed. The architecture contains frame detection, symbol timing estimation and signal power estimation. The estimated signal power can be used in AGC. The(More)
