Method for signal mapping and signal transmission with subcarrier shift schemes |
摘要 |
A signal mapping method and a signal transmission method applying a subcarrier shift method are described. A signal mapping method using shifted subcarriers includes shifting positions of data subcarriers by as much as a frequency band corresponding to half of spacing between data subcarriers on a frequency axis, and shifting positions of random access preamble subcarriers by as much as a frequency band corresponding to half of spacing between the data subcarriers and to a specific ratio of spacing between the random access preamble subcarriers, and mapping data and a random access preamble to the data subcarriers and the random access preamble subcarrier, respectively. Even when the spacing between the data subcarriers is a multiple of the spacing between the random access preamble subcarriers, DC distortion can be minimized. |
