Patent ID: 8620465

Claim:
A method for combining a first digital data set ( 20 ) of samples (A 0 , A 1 , A 2 , A 3 , A 4 , A 5 , A 6 , A 7 , A 8 , A 9 ) with a first size and a second digital data set ( 30 ) of samples (B 0 , B 1 , B 2 , B 3 , B 4 , B 5 , B 6 , B 7 , B 8 , B 9 ) with a second size into a third digital data set ( 40 ) of samples (C 0 , C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7 , C 8 , C 9 ) with a third size smaller than a sum of the first size and the second size, comprising the steps of: equating a first subset of samples (A 1 , A 3 , A 5 , A 7 , A 9 ) of the first digital data set ( 20 ) to neighboring samples of a second subset of samples (A 0 , A 2 , A 4 , A 6 , A 8 ) of the first digital data set ( 20 ) where the first subset of samples (A 1 , A 3 , A 5 , A 7 , A 9 ) and the second subset of samples (A 0 , A 2 , A 4 , A 6 , A 8 ) are interleaved, equating a third subset of samples (B 0 , B 2 , B 4 , B 6 , B 8 ) of the second digital data set ( 30 ) to neighboring samples of a fourth subset of samples (B 1 , B 3 , B 5 , B 7 , B 9 ) of the second digital data set ( 30 ) where the third subset of samples (B 0 , B 2 , B 4 , B 6 , B 8 ) and the fourth subset of samples (B 1 , B 3 , B 5 , B 7 , B 9 ) are interleaved, where the samples of the fourth subset (B 1 , B 3 , B 5 , B 7 , B 9 ) and the second subset of samples (A 0 , A 2 , A 4 , A 6 , A 8 ) have no samples corresponding in time, creating the samples (C 0 , C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7 , C 8 , C 9 ) of the third digital data set ( 40 ) by adding the samples (A 0 â€³, A 1 â€³, A 2 â€³, A 3 â€³, A 4 â€³, A 5 â€³, A 6 â€³, A 7 â€³, A 8 â€³, A 9 â€³) of the equated first digital data set to the, in the time domain, corresponding samples (B 0 â€³, B 1 â€³, B 2 â€³, B 3 â€³, B 4 â€³, B 5 â€³, B 6 â€³, B 7 â€³, B 8 â€³, B 9 â€³) of the equated second digital data set, embedding a first seed sample (A 0 ) of the first digital data set ( 20 ) and a second seed sample (B 1 ) of the second digital data set ( 30 ) in the third digital data set ( 40 ).
