Using convolutional decoding to improve time delay and phase estimation in digital communications
Patent

OSTI ID:978856
- Albuquerque, NM
The time delay and/or phase of a communication signal received by a digital communication receiver can be estimated based on a convolutional decoding operation that the communication receiver performs on the received communication signal. If the original transmitted communication signal has been spread according to a spreading operation, a corresponding despreading operation can be integrated into the convolutional decoding operation.
