Data transmission and reception method and apparatus robust against phase noise for high efficiency satellite transmission
PS Kim, DG Oh - US Patent 9,008,094, 2015 - Google Patents
(57) ABSTRACT A data transmission and reception apparatus is used for a high efficiency
satellite transmission. The apparatus includes an initial phase calculation unit to calculate
initial phase infor mation using a preamble and a postamble of a data packet applied
thereto, a symbol transition calculation unit to per form forward and backward metric
operations using the ini tial phase information calculated by the initial phase calcula tion unit
and a pilot symbol in the data packet to calculate a symbol transition of the data packet, and …
