LDPC Tone Mapping Schemes for Dual-Sub-Carrier Modulation in WLAN |
| abstract |
A new lower density parity check (LDPC) tone mapper is proposed when DCM is applied for a given resource unit (RU) when LDPC is used as the channel control coding. For HE PPDU transmission with DCM, LDPC encoded streams are first modulated by a DCM constellation mapper. The modulated symbols of the lower half of the frequency segment and the modulated symbols of the upper half of the frequency segment are modulated using the same LDPC encoded bits using DCM mapping. The modulated symbols of the lower half of the frequency segment are mapped to lower half of the data subcarriers using DCM LDPC tone mapper. The modulated symbols of the upper half of the frequency segment are mapped to upper half of the data subcarriers using the same DCM LDPC tone mapper. Maximum frequency diversity for DCM can be achieved. |
