Improved and efficient EM channel estimation algorithm for MIMO-OFDM systems

Improved and efficient EM channel estimation algorithm for MIMO-OFDM systems

For multiple-input multiple-output with orthogonal frequency division multiplexing（MIMO-OFDM） systems,the error floor（EF） phenomenon at high signal noise rate（SNR） was induced by the expectation maximum（EM） channel estimation algorithm.In addition,the data transmission efficiency was declined obviou...
