Soft decoding algorithms for optimized JPEG 2000 wireless transmission over realistic MIMO-OFDM systems

作者：

Highlights：

• New transmission and coding strategies for JPEG 2000 wireless com-pressed images are proposed.

• A joint implementation of UEP, UPA, adaptive modulation and soft decoding techniques are also considered.

• Soft-inputs decoding techniques are used to decrease the error rates at the reception.

• A realistic time-varying MIMO channel provided by a 3D ray-tracing software is adopted.

• Results show a significant improvement in quality compared to non adaptive strategy.
