Title: Synchronization to pseudo random number sequence with sign ambiguity in communications systems
Inventor: CHLOMA ALEXANDRE
IPC: H04B1/707
Filed: 1996-06-26
Granted: 2001-05-08
Abstract: A method is disclosed for synchronizing, in the presence of sign ambiguity, to a pseudo random maximal length sequence having a characteristic polynomial of order k with a coefficients vector A given by: A = [1 a1 a2 ... ak-1 1] where each of the coefficients a1 to ak-1 is 1 for an intermediate tap location and otherwise is 0. A received symbol sequence is supplied to and shifted through a K = k + 1 stage shift register with P intermediate taps in positions determined by a coefficeints vector Ain given by: Ain = [1 <o>a</o>1 (a1Oa2) (a2Oa3) ... (ak-2Oak-1) <o>a</o>k-1 1] where <o>a</o>1 and <o>a</o>k-1 are the inverse of a1 and ak-1 respectively and O denotes a modulo-2 sum, whereby the shift register has P intermediate taps where P is a positive integer less than K. A respective correlation signal is recursively added at an input for the received symbol sequence and at each intermediate tap. Each correlation signal is produced by correlating the P + 1 signals from said input, intermediate taps, and output other than the signal to which the respective correlation signal is added. The invention is particularly applicable to pilot synchronization in CDMA terminals.

Title: Texturizing compositions for use in fat blends in food
Inventor: WESTER INGMAR
IPC: A23L33/20
Filed: 1997-11-03
Granted: 2007-01-02
Abstract: Fatty acid esters, such as the unsaturated fatty acid esters of sterols and/ or stanols, are used as a replacement for a substantial portion or all of the undesirable saturated and trans-unsaturated fats used as structure giving hardstocks in edible foods such as margarines, mayonnaise, cooking oils, cheeses, butter and shortening. Because of the similarity in the crytallinity and physical properties of the esters to those of the undesirable hardstock fats, the substitution or replacement contributes favorably to the flavor, texture and other sensory properties of the foods. Only the fatty acid portion of the phytosterol este rs defined herein as texturizing agent is digested or absorbed with the sterol part being unabsorbable, thereby resulting in a reduction in tota l caloric uptake. Furthermore, the phytosterol fatty acid esters reduce the absorption of both dietary and biliary cholesterol from the digestive tract, thereby lowering the blood serum cholesterol level, especially the LDL-cholesterol.
