Method and apparatus for processing a transmission signal in communication system

摘要

Disclosed are a method and apparatus for processing a transmission signal using a window function that changes a spectrum characteristic of a symbol. A transmission apparatus includes a symbol generator that generate a plurality of consecutive symbols, and a symbol windowing processor that is coupled with the symbol generator. The symbol windowing processor applies a first window function and a third window function that uses a difference between the first window and a second window, and changes a spectrum characteristic of each of the plurality of consecutive symbols, and processes neighboring symbols from among the plurality of consecutive symbols of which spectrum characteristics are changed, such that the symbols partially overlap one another.

主权项

1. A transmission apparatus, comprising:
a symbol generator configured to generate a first signal comprising a main-lobe and a side-lobe; and a symbol windowing processor operatively coupled with the symbol generator, wherein the symbol windowing processor is configured to: generate a second signal to attenuate the side-lobe by applying a window function to the first signal, wherein the window function is determined based on a parameter, wherein the parameter is adaptively determined according to a size of the side-lobe, and is determined based on a difference between the main-lobe and the side-lobe, wherein the window function is further determined by adding a first window function and a first function, wherein the first function is determined by multiplying the parameter and a difference between the first window function and a second window function, wherein the first window function is a triangular window function, and wherein the second window function is a hanning window function.
