摘要:
Certain embodiments provide methods that may allow for improvements in performance and power consumption by terminating the turbo decoding process early when one of at least two test criterion is satisfied in communications systems, including UMTS, WCDMA, and TD-DCMA.

A method and apparatus for enabling a low complexity DL receiver in a TD-SCDMA system is provided. The method may comprise receiving two or more signals from two or more cells, determining at least one of the two or more cells does not comprise colored noise, applying a white noise matrix approximation to each of the at least one of the two or more cells that does not comprise colored noise, applying a channel matrix approximation to the two or more received signals, and generating a MMSE coordination matrix using the white noise matrix approximation and the channel matrix approximation.

A method and apparatus for enabling an enhanced FDE in a TD-SCDMA system is provided. The method may comprise receiving one or more signals from one or more cells over one or more channels where each channel is described using a channel vector and a spreading vector, and where each signal includes one or more data blocks each including a number of symbols, converting the one or more received signals from a time domain into a frequency domain using a block FFT, inverting a covariance matrix, wherein the covariance matrix is derived from a linear convolution of the one or more channel vectors and the one or more spreading vectors, and determining one or more MMSE signals by manipulating the frequency domain one or more received signals by applying the inverted equivalent channel matrix.

A method of wireless communication includes receiving a wireless signal at a linear receiver, and iteratively computing an inverted covariance matrix in frequency domain, one channel code at a time. The method also includes computing receiver demodulation coefficients based on the inverted covariance matrix and the frequency domain channel estimate or time domain channel estimate. The method further includes deriving a transmitter symbol based on a received signal vector and the coefficients.

A method transforms a generalized parity check matrix representing a linear block binary code. First, an input generalized parity check matrix is defined for the linear block binary code. Auxiliary sets are formed from the input generalized parity check matrix and organized into a partially ordered set. The subsets of each auxiliary set are ordered in a list, and parity check equations are constructed from the list of ordered subsets. The parity check equations are translated into an output generalized parity check matrix, which can be used to decode a message encoded according to the linear block binary code.

The present disclosure describes methods and apparatuses for improved transport block decoding in devices capable of wireless communication, which may include user equipment and network entities. For example, the present disclosure presents methods and apparatuses for decoding a code block from a plurality of code blocks corresponding to a transport block, obtaining a reliability indicator that identifies a reliability of the decoding of the code block, comparing the reliability indicator to a reliability threshold, and determining whether to decode a subsequent code block from the plurality of code blocks based on the comparing. Furthermore, these methods and apparatuses may include determining not to decode at least one subsequent code block of the transport block where the comparing indicates that the reliability indicator is less than the reliability threshold. As such, device power is not unnecessarily consumed by decoding likely superfluous code blocks.
