Title (EN) DIFFERENTIAL ENCODED M-PSK IN A WIRELESS COMMUNICATION SYSTEM
(FR) M-PSK CODÉ DIFFÉRENTIEL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract:
(EN) Embodiments herein relate to a method performed by a transmitting device for handling communication of data towards a receiving device in a wireless communications network. The transmitting device encodes first data bits mapped to constellation symbols to generate differentially encoded M:ary – Phase Shift Keying, M-PSK, symbols in a frequency domain, which data bits modulate one or more first Orthogonal Frequency Division Multiplexing, OFDM, symbols in a packet. The transmitting device further repeats at least a part of the differentially encoded M-PSK symbols; and transmits, to the receiving device (10), a packet comprising the differentially encoded M-PSK symbols and the repeated at least part of the differentially encoded M-PSK symbols.
(FR) Les mode de réalisation de la présente invention concernent un procédé réalisé par un dispositif de transmission pour gérer la communication de données vers un dispositif de réception dans un réseau de communication sans fil. Le dispositif de transmission code des premiers bits de données mappés à des symboles de constellation pour générer des symboles codés de manière différentielle par modulation par déplacement de phase M-ary (M-PSK) dans un domaine de fréquence, lesquels bits de données modulent un ou plusieurs premiers symboles de multiplexage par répartition orthogonale de la fréquence (OFDM) dans un paquet. Le dispositif de transmission répète en outre au moins une partie des symboles M-PSK codés de manière différentielle et transmet, au dispositif de réception (10), un paquet comprenant les symboles M-PSK codés de manière différentielle et la partie répétée des symboles M-PSK codés de manière différentielle.
