QUADRATURE IMBALANCE MITIGATION USING UNBIASED TRAINING SEQUENCES |
摘要 |
A system and method are provided for transmitting an unbiased communications training sequence. The method generates an unbiased training sequence in a quadrature modulation transmitter. The unbiased training sequence represents a uniform accumulated power evenly distributed in the complex plane. As a result, training information in the time domain is sent via an in-phase (I) modulation path having an accumulated power. Training information in the time domain is sent via a quadrature (Q) modulation path having an accumulated power equal to the I modulation path power. Also provided are system and method for calculating an unbiased channel estimate from a received unbiased training sequence. |
