Abstract
A method of operating a receiver to determine a bad frame indication (BFI) of a received speech block includes decoding speech information bits of the received speech block; re-encoding the decoded speech information bits; comparing the received speech information bits with the corresponding decoded and re-encoded speech information bits to calculate a number of erroneous bits; determining a mode information of the received speech block; calculating a signal quality measurement of the received speech block; calculating a block quality metric according to the mode information, wherein the block quality metric is related to both the number of erroneous bits and the signal quality measurement; and setting the BFI of the received speech block according to the block quality metric.
