Why is it important?
Partial transmit sequence technique was exploited to obtain a novel phase rotation set. Implementing this phase rotation set into 80 MHz system of the VHT WLAN IEEE802.11ac's preamble reduced the PAPR of the signal, significantly. It was 1. 4 dB lower than the PAPR of conventional extension of IEEE 802.11ac 80 MHz and even 1.6 dB lower than the PAPR of HT WLAN IEEE802.11n 40MHz. This allows the use of cheaper amplifier, more economic.
Perspectives
We hope this research will contribute in VHT WLAN based on IEEE 802.11ac 80MHz, Very high throughput by using cheaper amplifier.
