Abstract: A method for crystallizing aqueous carbohydrate-containing substances, comprising: purifying the aqueous substance containing carbohydrates; mixing said aqueous substance with a water-absorbing medium; distributing the above mixture in a layer on a high temperature resistant container; heating the mixture layer of the previous step in a microwave apparatus; cooling the mixture layer; re-heating and cooling the mixture layer until it reaches a humidity of 2 to 4%; spraying the crystallized mixture-layer, removing the water-absorbing medium from the crystals obtained; and recovering said crystals. A crystallized or granular product obtained by such a crystallization method.

Abstract: A polar encoder kernel, a communication unit, an integrated circuit and a method of polar encoding are described. The polar encoder kernal is configured to receive one or more bits from a kernal information block having a kernal block size of N; and output one or more bits from a kernal encoded block having a block size that matches the kernal block size N; wherein the polar encoder kernal comprises a decomposition of a polar code graph having multiple columns that are processed by a reused single datapath, at least one of said multiple columns contains two or more stages and where each column of the multiple columns is further decomposed into one or more polar code sub-graphs and is configured to process encoded bits one polar code sub-graph at a time.

Abstract: A polar coder circuit is described. The polar coder circuit comprises one or more datapaths; and at least one logical three-dimensional, 3D, memory block coupled to the one or more datapaths and comprising a number of one or more random access memories, RAMs, of the logical 3D memory block as a first dimension, wherein the one or more RAMs comprise(s) a width of one or more element(s) as a second dimension and a depth of one or more address(es) as a third dimension and wherein the first dimension or the second dimension has a size 2sd, where sd is a number of stages in a datapath of the one or more datapaths.

Abstract: An electronic device configured to perform polar coding is described. The electronic device includes a bit pattern generator (3403) configured to successively perform a bit pattern generation process over a series (t=?n/w?) of clock cycles; and a counter (c, 4203), operably coupled to the bit pattern generator (3403) and configured to count a number of successive bit pattern generation sub-processes over the series (t=?n/w?) of clock cycles. The bit pattern generator (3403) is configured to: provide a successive sub-set of (w) bits from a bit pattern vector (bk,n) in each successive t=?n/w? clock cycle; where the bit pattern vector comprises n bits, of which ‘k’ bits adopt a first binary value and n?k bits adopt a complementary binary value.
