| 摘要 |
<p>The present invention introduces a MIMO transmission system comprising an envelope detector that obtains distortion information of a power amplifier with an envelope detector, which is simply implementable, thereby minimizing the cost of implementing a feedback pathway, and a method of designing a predistorter constituting a MIMO transmission system that designs the predistorter included in the MIMO transmission system. The MIMO system comprises: a first transmitter; a second transmitter; a feedback pathway unit; and an adaptation algorithm implementation unit. The method for designing a predistorter constituting the MIMO transmission system is used for compensating the distortion of a transmission signal outputted from the MIMO transmission system described in claim 4, and the method comprises the steps of: inputting a training signal; generating an error signal; detecting an envelope signal; generating a digital error signal; and generating a control signal.</p> |
