Using both bit error rate (BER) and a received signal strength indicator (RSSI)in channel estimation for mobile telephones |
摘要 |
A radio channel estimation method includes a combination of BER (bit error rate) estimation and RSSI (received signal strength indicator) estimation. The RSSI and the BER are detected from a received signal through a radio channel, and then the radio channel is estimated based on the RSSI and the BER. A quality of the radio channel is estimated to be degraded unless the BER meets a first criterion and the RSSI meets a second criterion. The BER meets the first criterion when an average number of times during a time period that the BER exceeds a maximum value is smaller than a first threshold value. The RSSI meets the second criterion when an average number of times during a time period that the RSSI is below a minimum value is smaller than a second threshold value. |
