Query: An Efficient Partial Sums Generator for Constituent Code based
  Successive Cancellation Decoding of Polar Codes   This paper proposes the architecture of partial sum generator for constituent
codes based polar code decoder. Constituent codes based polar code decoder has
the advantage of low latency. However, no purposefully designed partial sum
generator design exists that can yield desired timing for the decoder. We first
derive the mathematical presentation with the partial sums set $\bm{\beta^c}$
which is corresponding to each constituent codes. From this, we concoct a
shift-register based partial sum generator. Next, the overall architecture and
design details are described, and the overhead compared with conventional
partial sum generator is evaluated. Finally, the implementation results with
both ASIC and FPGA technology and relevant discussions are presented.
