| 摘要 |
The present invention relates to a mobile terminal for efficiently measuring a carrier to noise and interference ratio (CNIR) in an orthogonal frequency division multiplexing (OFDM) mobile communication system and a CNIR method thereof. The mobile terminal includes a frequency offset and frame detector for detecting frame timing information and frequency offset from a received signal, a demodulator for demodulating the received signal by using the detected frame timing information and frequency offset, a subchannel separator for separating a data symbol from symbols outputted by the demodulator, a channel estimating and equalizing unit for estimating and equalizing a channel for the corresponding subchannel from the data symbol, and a CNIR measuring unit for transmitting a measured current CNIR to the base station. |
