Abstract
A method for generating code sequences having good correlation properties comprising steps of selecting a code length comprising a number of chips, selecting a ruler which defines the position of non-zero values within the chips, and overlaying the non-zero values with an amplitude pattern.
Claims1
A method of generating communication signals comprising the steps of:
- selecting a code comprising a set of chips, wherein each chip of the set of chips is one of a positive or negative nonzero value and a zero value, the set of chips are positioned in accordance with a first ruler of a set of rulers, the first ruler being substantially orthogonal to each other ruler in the set of rulers such that no two chips having non-zero values are adjacent and a first chip with a positive value and a second chip with a negative value are placed in accordance with a first pattern of a set of patterns corresponding to time-shifted versions of the first pattern, each pattern of the set of patterns substantially orthogonal to each other pattern of the set of patterns;
- generating a signal using the code, wherein the nonzero values correspond to an amplitude of the signal;
- and
- transmitting the generated signal.
