摘要:
In various aspects, the disclosure describes systems and methods for decoding of convolutionally encoded signals representing, for example, telecommunications signals such as command or content signals used in digital telecommunications. In various embodiments such aspects of the disclosure provide systems and methods for improving the efficiency, speed, and power consumption of such processes by providing architectures and methods for processing various parts of the encoded data records in parallel, using multiple and optionally specially-designed, dedicated memory registers and multiplexers.
摘要:
A method for estimating channel state information (CSI) for a communication channel is disclosed. Theoretical channel capacities are calculated using combinations of rank indicator (RI) and precoding matrix index (PMI) values. A number of these theoretical channel capacities are selected and used for determining an optimum combination of channel quality indicator (CQI) values, RI values and PMI values. This combination of values is subsequently transmitted as CSI. 1.
摘要:
A method for channel estimation includes receiving data at a number of frequency intervals in a frequency band over a number of first time intervals. A first set of channel estimates is determined (152) for each pilot symbol (106) within the data over a second time interval comprising at least one first time interval, and time-direction interpolation (154) is performed to determine a second set of channel estimates for a number of data portions in a frequency interval using the first set of channel estimates. The frequency interval comprises a data portion comprising a pilot symbol (106). Frequency-direction interpolation (156) is performed to determine a third set of channel estimates for each first time interval. The time-direction interpolation (154) and the frequency-direction interpolation (156) can be performed in reverse order with the channel estimates generated by the frequency-direction interpolation (156) being used as inputs for time-direction interpolation (154).
