  • Publication number: 20140201594
    Abstract: In an example implementation of this disclosure, a message passing low density parity check (LDPC) decoder may, during decoding of a first group of bits, lock a first variable node upon a bit-value probability of the first variable node reaching a determined threshold, and lock a first check node upon all variable nodes connected to the first check node being locked. The LDPC decoder may cease decoding the first group of bits upon all variable nodes of the LDPC decoder being locked, all check nodes of the LDPC decoder being locked, reaching a maximum number of iterations, or reaching a timeout. During a particular iteration of the decoding of the first group of bits in which the first variable node is locked, the LDPC decoder may refrain from generating a bit-value probability for the locked first variable node.

  • Publication number: 20140155009
    Abstract: A circuit includes, in part, a receiver, a received signal strength indicator (RSSI), and an oscillator. The receiver receives an incoming signal and an oscillating signal. The RSSI is responsive to the receiver and generates an output signal representative of the strength of the incoming signal. The oscillator receives different biasing conditions in response to different outputs of the RSSI. The oscillator generates the oscillating signal received by the receiver. The oscillator receives a first biasing condition when the incoming signal is detected as having a strength lower than or equal to a predetermined threshold value and a second biasing condition when the incoming signal is detected as having a strength higher than the predetermined threshold value. The first biasing condition may be defined by a first current, and the second biasing condition may be defined by a sum of the first current and a second current.
