摘要： The disclosed apparatus, structures, and methods are directed to a wireless receiver. The configurations presented herein employ a structure operative to receive a plurality of analog signals, a signal encoder configured to encode the plurality of received analog signals into a single encoded analog composite signal based on a coding scheme operating under a first code rate, a signal reconstruction module configured to segregate and reconstruct the single encoded digital composite signal into a re-encoded digital composite signal in accordance with the coding scheme operating under a second code rate. In addition, a signal decoder configured to decode the digital composite signals based on the coding scheme operating under the second code rate, and to output digital signals, in which each digital signal in the plurality of digital signals corresponds to a respective analog signal of the plurality of received analog signals.

摘要： The disclosed systems, structures, and methods are directed to a wireless receiver. The configurations presented herein employ a signal encoding module to encode a plurality of received analog signals with an orthogonal code set and combine the encoded analog signals into a single encoded analog composite signal, an analog-to-digital conversion unit to convert the single encoded analog composite signal into a single encoded digital composite signal containing constituent digital signals. The presented configurations also include a bank of multiple successive interference cancellation (SiC) modules to sequentially remove the constituent digital signals from the single encoded digital composite signal until a single constituent digital signal remains and a decoding module configured to decode the remaining constituent digital signal from the single encoded digital composite signal.

摘要： A self-timed parallelized multi-core processor has an instruction decoder unit for receiving a program code instruction, determining an operating code and latency for the instruction, and assigning a loop index to the instruction. An instruction decomposer creates a primitive by decomposing the instruction, replacing the loop index with a core index, and broadcasting the primitive. Self-timed processing cores each having a unique core index compare the core index to their unique processing core index. The processing cores act on the primitive when their processing core index is within a threshold of the core index.
