摘要： Methods and apparatus are provided for secure communication techniques in a communication system. The system can include a first device (10) which communicates with a second device (10’) over a channel. A security association can be established during a first session between the devices via an asymmetric key exchange (132). The security association comprises a Traffic Encryption Key (TEK) and a first state vector. The TEK comprises a shared, secret symmetric key. The security association is stored in each of the devices for use during a second session between the devices to expedite security association establishment during call set-up of the second session (428). The security association can be associated with the second device in the first device, and with the first device in the second device. An updated state vector can be generated at the first device. A second session can be established between the first device and the second device by using the TEKs from the first session and the updated state vector. The security association can be used to encrypt (4) voice packets being sent from the first device to the second device. The security association and updated state vector can then be used to decrypt (6) the encrypted voice packets received by the second device from the first device.

The processor calculates (504) an index into a final metrics buffer (702), the index determined from a position of the channel metric within an interleaved frame of data. The processor places (506) a value derived from the channel metric into the final metrics buffer at a location defined by the index. A corresponding method and apparatus as well as communications receiver utilizing the processor (604) are described.

摘要： A system, wireless device (402) and method receive a set of soft metrics (614) associated with a block of symbols during a predetermined time interval, use the set of soft metrics (614) to form an initial interference power estimate, form a moving-average estimate of interference power (616) corresponding to each predetermined time interval, and scale the set of soft metrics (614) according to the corresponding interference power estimate resulting in a set of scaled metrics (618). Then they limit the dynamic range of the set of scaled metrics (618), linearly quantize the limited metrics, and output the linearly quantized limited metrics (628) to a memory buffer. The size of the memory buffer containing the linearly quantized limited metrics (628) is smaller than the size of a memory buffer required to store the received soft metrics (614). The linearly quantized limited metrics (628) are then used as input to a decoder.
