摘要： A transmitting device generates a data block including a first field having a first plurality of bits that includes an error detection portion and a second field having a second plurality of bits; selects an error injection mask based on the second plurality of bits; modifies the first plurality of bits with the error injection mask to generate a modified first plurality of bits; and transmits the data block to a receiving device. The receiving device decodes the second plurality of bits to generate decoding results; selects an error injection mask based on the decoding results; modifies the first plurality of bits using the error injection mask to generate a modified first plurality of bits that includes a resultant error detection value indicated in the error detection portion; and detects whether the decoding results for the second field are correct based on the resultant error detection value.

摘要： A system and method for receiving data and control messages comprised of a series of data units is provided. The data units comprising each message are structured to follow a particular sequence, such as zero or more data units of a first type followed by one or more data units of a second type, which may then followed by data units of one or more other predetermined types. Upon receiving a data unit of a first or second type, a number of “units to follow” is determined from information provided in the received data unit. A number of subsequently received data units are then forced to be processed as one of the first type, the second type, or other predetermined type in accordance with the known structure of the message. The number of subsequently received data units that are forced to be processed as one of these types is based on the determined number of units to follow.

摘要： A received synchronization pattern is compared against first and second known synchronization patterns. If the received pattern is of the first known pattern, the payload is processed as voice; and if the received pattern is of the second known pattern, the payload is processed as non-voice. In an alternative, the received pattern is compared against first and second known synchronization patterns. If the received pattern is of the first known pattern, a first operating mode is selected, and if the received pattern is of the second known pattern, a second operating mode is selected.
