How to interpret the values returned using FE_READ_BER and FE_READ_SNR in a frontend IOCTL?
The definition of BER is (error bit)/(total bit) in a time interval, while the definition of SNR is (signal power)/(error power). In the DVB Frontend API I see that BER is a uint32_t and SNR ia a uint16_t. For example, with a poor signal I got the following values: Bit error rate: 304146 Signal strength: 38576 SNR: 22359 Bit error rate: 316097 Signal strength: 37912 SNR: 21588 The interval between two readings is 5 seconds. Why BER is a (so) big number? How to express SNR with dB?
