SYSTEMS AND METHODS FOR INCLUDING AN IDENTIFIER WITH A PACKET ASSOCIATED WITH A SPEECH SIGNAL |
摘要 |
A method for including an identifier with a packet associated with a speech signal is described. A signal is received. The signal is partitioned into a plurality of frames. A frame of the signal is encoded into a packet. A determination is made if the packet is encoded as a wideband packet or a narrowband packet. An identifier is packed in the packet based on the determination. The packet is transmitted. At least two illegal values are provided from an N-bit parameter, wherein at least one bit from the N-bit parameter is used to carry information. A number of bits from the N-bit parameter that are used to carry information is equal to log<SUB>2</SUB>(X), wherein X is the number of illegal values provided from the N-bit parameter.
