Claims18
A data transmission method, comprising the following steps:
- determining a transmission resource to be used and a complex-valued spreading sequence to be used;
- processing a data symbol to be sent by using the complex-valued spreading sequence to generate a symbol sequence;
- and
- sending the symbol sequence through the transmission resource,
- wherein each element of the complex-valued spreading sequence is a complex number, and values of a real part and an imaginary part of each element are both from an M-element real number set, wherein the M is an integer greater than or equal to 2, and the M-element real number set is selected from:
- a set formed by M integers within a range of [−(M−1)/2, (M−1)/2], wherein the M is an odd number;
- a set formed by M odd numbers within a range of [−(M−1), (M−1)], wherein the M is an even number;
- a set formed by M real numbers obtained through multiplying respectively M integers within a range of [−(M−1)/2, (M−1)/2] by specified coefficient(s), wherein the M is an odd number;
- and
- a set formed by M real numbers obtained through multiplying respectively M odd numbers within a range of [−(M−1), (M−1)] by specified coefficient(s), wherein the M is an even number.
