Title: Method and apparatus for computing soft decision input metrics to a turbo decoder
IPC: H04L27/22
Filed: 2001-03-07
Abstract: A method and apparatus for computing soft decision input metrics to a turbo decoder includes circuits associated with eight-ary phase shift keyed (8PSK) modulation and sixteen-ary quadrature amplitude modulation (16QAM). In both implementations log-likelihood ratio (LLR) metrics on code symbols are estimated as products of various constant values and various combinations of the in-phase and quadrature components of a demodulated soft decision. In the implementation associated with the 16QAM modulation scheme, an estimate of the carrier-signal-to-interference (C/I) ratio is also used to estimate some of the LLR metrics. Estimates of the LLR metrics may also be obtained in association with generalized square QAM and M-ary PSK modulation schemes including, e.g., 64QAM, 256QAM, and 16PSK.

The selected code index value is recorded in the first buffer(330). The second buffer(340) records added bits. An AND unit(350) inputs 4 bits and the added bits from the first and second buffers(330,340), and performs an AND operation for a combined value of the bits by a chip count value, then outputs an 8-bit code arrangement to an XOR unit(360).

CONSTITUTION: An outer frame(100) has an inner surface forming a space and a reflection material is coated on a bottom plane and a side of the outer frame. A printed circuit board(200) is located on the bottom of the outer frame and is routed by silk printing and a white silk reflecting a light is coated on at least one plane of the printed circuit board. At least one light emitting diode(300) has a light emitting part toward the plane of the printed circuit board coated with the white silk, and the light emitting part is separated from the printed circuit board and is fixed to the printed circuit board. A complex epoxy resin(500) is adhered to a side of the outer frame and includes a fluorescent coloring pigment molded in the outer frame. And a transparent coating material(600) is coated on the complex epoxy resin.
