Systems and methods for performing efficient blind decoding at a wireless receiver

摘要

Systems and methods for performing efficient blind decoding. A first plurality of decision metrics corresponding to a first repetition of periodic decoding information is stored. The first plurality of decision metrics is grouped into sequential portions. A plurality of combined versions of the sequential portions is stored into combining buffers arranged in sequence. Each combined version is associated with a different sequence of timing information. A first of the plurality of combined versions stored in a first of the combining buffers is combined with a second version of a second plurality of decision metrics that corresponds to a second repetition of the periodic decoding information. The second version is associated with timing information adjacent in the timing information sequence to the timing information associated with the first combined version. The data is decoded based on information in the combining buffers.

1. A method for decoding data, the method comprising:
receiving a first decision metric associated with first timing information; accumulating, using a storage device, a first portion of the first decision metric with an adjacent second portion of the first decision metric; receiving a second decision metric different from the first decision metric associated with second timing information different from the first timing information; accumulating, using the storage device, portions of the second decision metric with the accumulated portions of the first decision metric; determining how many antennas correspond to data based on information stored in the storage device; determining an instance of timing information corresponding to a start of a period of periodic decoding information, wherein the timing information includes the first timing information or the second timing information; and configuring receiver decoding circuitry based on how many of the antennas are determined to correspond to the data and the instance of the timing information.
