    Abstract: An apparatus and method for high throughput unified turbo decoding comprising loading data from a first data window; computing a first forward state metric using the data from the first data window; storing the first forward state metric in a memory; computing a first reverse state metric using the data from the first data window; storing the first reverse state metric in the memory; and computing the log likelihood ratio (LLR) of the first forward state metric and the first reverse state metric. In one aspect, the above-mentioned steps are repeated with data from a second data window. In another aspect, extrinsic information for the first data window associated with the unified turbo decoding is computed.

    Abstract: Method and apparatus for decoding code words received over a communication channel are disclosed. A radius-adaptive sphere decoding methodology reduces the number of operations in sphere-constrained search. Imposing probabilistic noise constraint on top of sphere constraint, particularly at an early stage, provides a more stringent necessary condition. Hence, many branches that are unlikely to be selected are removed in the early stage of sphere search. The trade-off between computational complexity and performance can be controlled by adjusting the pruning probability.

    Abstract translation: 公开了一种用于解码通过通信信道接收的码字的方法和装置。 半径自适应球体解码方法减少了球面约束搜索中的操作次数。 特别是在早期阶段，将概率性噪声约束强加在球体约束之上，提供了更严格的必要条件。 因此，不可能选择的许多分支在球搜索的早期阶段被去除。 可以通过调整修剪概率来控制计算复杂度和性能之间的折衷。

    Abstract: TDD devices may transmit using multiple antennas. First and second antennas having first and second receive conditions may receive a communication. In an aspect, first and second transmit conditions for the first and second antennas may be determined based on the first and second receive conditions. In an aspect, the first and second transmit conditions may be compared to select the first or second antenna for transmissions. In an aspect, the first and second receive conditions may be compared to select the first or second antenna for transmissions. In an aspect, first and second transmission conditioning values, which may determine transmission powers, may be determined based on the first and second receive conditions. A first transmission chain, associated with an active radio access technology (RAT) or carrier, and a second transmission chain, associated with an inactive RAT or carrier, may be activated to send transmissions from the first and second antennas.
