摘要

在0.13 μm CMOS库中实现了一种多输入多输出(4×4)正交频分复用(OFDM)调制解调器，该调制解调器具有单符号锁定时序恢复、抗I/Q错配频率恢复、频率相关I/Q错配估计和自适应均衡功能。该芯片占地4.6×4.6 mm2，在1.2 V时消耗62.8 mW。

A 62.8 mW 4×4 MIMO-OFDM modem with one-symbol-locked timing recovery, frequency-dependent I/Q mismatch estimation and adaptive equalization

A 4×4 multi-input multi-output (MIMO) orthogonal frequency-division multiplexing (OFDM) modem with one-symbol-locked timing recovery, anti-I/Q mismatch frequency recovery, frequency-dependent I/Q mismatch estimation and adaptive equalization is implemented in 0.13-μm CMOS library. This chip occupies 4.6×4.6 mm2 and consumes 62.8 mW at 1.2 V.
