Improving MIMO-OFDM-based DVB-H systems performance using LDPC codes

Handheld devices are becoming more and more popular across the world although there are often still reception problems. To solve these reception issues, technology such as multiple antenna systems are being investigated. One drawback to such systems is that of peak to average power ratio - an effect where out of band radiation can cause distortions in the transmitted stream especially where combined with orthogonal frequency division multiplex (the technology behind modern hand-held television). This paper will show that by combining powerful error correction coding (in this case the low density parity check), it is possible to lower the peak to average power ratio with minimal increase in complexity.
