Method and apparatus for transmitting and receiving signal

摘要

Provided are a method and an apparatus for transmitting a signal suitable for an indoor environment. The method for transmitting a signal according to an exemplary embodiment of the present invention includes: preprocessing a signal using a signal power to sidelobe power ratio (SSR) parameter defining a signal to sidelobe ratio to minimize an inter-symbol interference and prevent performance deterioration due to reduction in signal strength; and transmitting the preprocessed signal to a receiving apparatus through a predetermined channel.

1. A method for transmitting a signal, comprising:
preprocessing a signal to be transmitted using a time reversal (TR) filter applied with a weighted value to reduce an inter-symbol interference of the signal and relieve performance deterioration due to reduction in signal strength, wherein the weighted value is calculated using a signal power to sidelobe power ratio (SSR) parameter defining a signal to sidelobe ratio, and wherein the SSR parameter is generated by the TR filter applied with the weighted value and a predetermined channel; and transmitting the preprocessed signal to a receiving apparatus through a predetermined channel.
