Error tolerance in wireless OFDM data transmission using signal quality driven symbol Re-mapping

In the consumer electronics market, the need for error tolerance in wireless systems is increasing especially from I-Q imbalances and non-linearity in RF front-end. In most applications such as encoded image transmission, not all bits are equally important. However, current error tolerance schemes g...

Summary:In the consumer electronics market, the need for error tolerance in wireless systems is increasing especially from I-Q imbalances and non-linearity in RF front-end. In most applications such as encoded image transmission, not all bits are equally important. However, current error tolerance schemes give equal importance to all transmitted bits. In this paper, an OFDM data transfer methodology that has the least impact on image data in the presence of persistent bit errors due to I-Q imbalances and non-linear compression is proposed.
