摘要： A voltage regulation circuit includes a voltage conversion module, an LED driving module and a control module. The voltage conversion module is operable to receive and convert the first voltage to a second voltage. Each LED driving loop of the LED driving module has a current regulator and an LED string. The control module is operable to output a control signal according to the received input signal which reflects the current flowing through the LED driving module. The voltage conversion module regulates the second voltage according to the control signal, such that the regulated second voltage still keeps the brightness of the LED string of each LED driving loop unchanged.

摘要： A method for efficient decoding of block product code format signals, using a (22p)QAM signal constellation for mapping of a received signal, with p=2, 3, 4, 5, . . . A received signal value rx, corresponding to an x=I or x=Q coordinate, is converted to a p-tuple (B(p-1)x, . . . , B0x) corresponding to a “closest” I-coordinate or Q-coordinate numerical value, and a p-stage algorithm is applied to the signal values rx and to the p-tuples (B(p-1)x, . . . , B0x) to determine a p-tuple (r(p-1)x, . . . , r0x) representing a decoded p-bit value for the received signal value rx. Depending upon a communication channel parameter Eb/N0 and the bit error ratio BER associated with each of the p bits, the received signal values rx may be suitable for some or all communications activities (e.g., HDTV, SDTV, mobile comm).

摘要： A Viterbi decoder generates a branch metric table from first and second data signals taken at two sample times and provides selected branch metrics to an add/compare/select circuit in response to branch indices from a branch index generator. The branch metrics in the branch metric table are the sixteen combinations of the sum of the first and second parallel data signals at first and second sample times and the inverse of such signals. The branch index generator generates the branch indices in response to a received state from the add/compare/select circuit, convolutional code polynomials and the possible states of a radix-4 trellis. The add/compare/select generates a survivor path decision based on the selected branch metrics.
