Satu kaedah untuk menganggar kovarians saluran daripada pautan atas menerima kuasa isyarat untuk penghantaran pautan bawah prapengekodan dalam sistem wayarles dupleks pembahagian frekuensi berbilang input (MIMO) berbilang input (FDD) dicadangkan. Tidak seperti skim prapengekodan MIMO yang lain, skim yang dicadangkan tidak memerlukan saluran maklum balas atau simbol perintis, iaitu pengetahuan tentang kovarians saluran disediakan di pemancar pautan bawah melalui anggaran terus daripada kuasa isyarat yang diterima pautan atas. Ini membawa kepada kerumitan yang rendah dan kecekapan sistem yang lebih baik. Ia menunjukkan bahawa skim yang dicadangkan menunjukkan prestasi yang lebih baik atau setanding dengan skim praktikal yang lain dan hanya mengalami kemerosotan prestasi yang sedikit jika dibandingkan dengan sistem yang mempunyai pengetahuan sempurna tentang kovarians saluran.

Abstract: A method for estimating channel covariance from the uplink received signal power for downlink transmit precoding in multiple-input multiple-output (MIMO) frequency division duplex (FDD) wireless systems is proposed. Unlike other MIMO precoding schemes, the proposed scheme does not require a feedback channel or pilot symbols, i.e. knowledge of the channel covariance is made available at the downlink transmitter through direct estimation from the uplink received signal power. This leads to low complexity and improved system efficiency. It is shown that the proposed scheme performs better or on par with other practical schemes and only suffers a slight performance degradation when compared with systems with perfect knowledge of the channel covariance.
