Abstract: Disclosed are various embodiments providing processor configured to determine a received signal strength indication (RSSI) value for each of the plurality of channel taps. The processing circuitry identifies a maximum RSSI value among the RSSI values and may adjust a variable threshold range according to the maximum RSSI value. The RSSI value for each channel tap may be scaled according to a corresponding per tap noise power.

Abstract: Disclosed are various embodiments that provide turbo decoding implemented as at least a portion of baseband processing circuitry. An input bit stream may be divided into a set of code blocks and a first code block may be separated from the set of code blocks. A hybrid automatic repeat request (HARQ) process is performed on the first code block to generate a processed first code block. The processed first code block is stored in an incremental redundancy (IR) buffer. A turbo decoding process is performed on the processed first code block to generate decoded first code block data and the decoded first code block data is stored in an external memory. The processed first code block is removed from the IR buffer for decoding a remaining portion of the set of code blocks.
