Patent ID: 7403574

Claim:
A method of generating a scrambled signal having real symbols I S,k and imaginary signals Q S,k from a signal having real symbols I k and imaginary symbols Q k , comprising the steps of: generating a real part of a k th element of a complex scrambling sequence (d I,k ); generating an imaginary part of the k th element of the complex scrambling sequence (d Q,k ); generating a scrambling phase multiplier n k according to: n k =2 d I,k +d Q,k ; and generating the scrambled signal: I S , k + j ⁢ ⁢ Q S , k = ( I k + j ⁢ ⁢ Q k ) ⁢ ⅇ j ⁡ ( 2 ⁢ ⁢ π ⁢ ⁢ n k 4 ) .
