Patent ID: 7089274

Claim:
An electrical device for generating a pseudo random noise (PN) output sequence (Z t ) comprising: a sequence generator to output a plurality of sequence values (X 2i , X 2i+1 ) based on a step control signal (S t ); wherein the plurality of sequence values is two; a control and selection system coupled to the sequence generator adapted to select one of the plurality of sequence values (X 2i , X 2i+1 ) from the sequence generator based on a select value (M t ), wherein the select value (M t ) is provided based on a clock control value or signal (C t ) and a previously generated select value (M t−1 ); wherein the select value (M t ) is calculated as M t =(C t +M t−1 ) MOD 2; and a step control of the control and selection system adapted to provide the step control signal (S t ) to the sequence generator, wherein the step control signal (S t ) is provided based on the clock control value or signal (C t ) and the previously generated select value (M t−1 ) wherein the step control signal (S t ) is calculated as S t =(C t +M t−1 ) DIV 2.
