摘要： Methods, systems, and devices for wireless communications are described. In some systems, a device, such as an internet of things (IoT) device, may include a configuration or software (e.g., in baseband) that is common for multiple applications of the device. In some aspects, the device may select a setting for at least some if not each of a set of parameters associated with or defining a device profile of the device based on an application of the device. The device may perform a mapping procedure to map the settings for the parameters associated with the device profile to one or more baseband configurations or baseband handles and the device may customize the baseband of the device using the one or more baseband configurations. As such, the device may operate or communicate using the baseband that is customized based on the device profile and application of the device.

摘要： An electronic receiver may generate a differential detection sequence based on a received symbol sequence and based on a m-symbol delayed version of the received symbol sequence, where in is an integer greater than 1. The particular differential detection sequence may be a result of an element-by-element multiplication of the particular received symbol sequence and the conjugate of an in-symbol delayed version of the particular received symbol sequence. The receiver may calculate differential decision metrics based on the differential detection sequence and based on a set of differential symbol sequences generated from the set of possible transmitted symbol sequences. The receiver may generate a decision as to which of a set of possible transmitted symbol sequences resulted in the received symbol sequence, where the decision is based on the differential decision metrics and the set of possible transmitted symbols sequences.

摘要： A device of dynamic communication of information allows, on the average, non-integer bits per symbol transmission, using a compact code set or a partial response decoding receiver. A stream of selectable predetermined integer bits, e.g., k or k+1 data bits, is grouped into a selectable integer number of bit vectors which then are mapped onto corresponding signal constellations forming transmission symbols. Two or more symbols can be grouped and further encoded, so that a symbol is spread across the two or more symbols being communicated. Sequence estimation using, for example, maximum likelihood techniques, as informed by noise estimates relative to the received signal. Each branch metric in computing the path metric of a considered sequence at the receiver is weighted by the inverse of the noise power. It is desirable that the constellation selection, sequence estimation and noise estimation be performed continuously and dynamically.

摘要： As disclosed herein, a “super receiver” structure enriches the information provided for decoding modem bits included in a received sequence of symbols. In particular, an equalizer circuit provides joint metrics to a decoder circuit, where the joint metrics advantageously reflect joint bit probabilities. However, the metrics are computed without need for complex joint probability calculations. The decoder circuit “fuses” the joint metrics with corresponding side information, which indicates the likelihood that one or more bits represented by the joint metric take on a particular value. Such fusing biases the soft value estimation for the other bits represented by the joint metric, thus enabling the decoder to operate on refined soft values in its bit decoding operations.
摘要翻译：如本文所公开的，超级接收机结构丰富了用于解码包含在所接收的符号序列中的调制解调器位的信息。特别地，均衡器电路向解码器电路提供联合度量，其中联合度量有利地反映了联合位概率。然而，在不需要复杂联合概率计算的情况下计算度量。解码器电路使联合度量与相应的侧面信息融合，该信息指示由联合度量表示的一个或多个比特具有特定值的可能性。这种融合偏置了由联合度量表示的其他位的软值估计，从而使解码器能够在其位解码操作中对精细的软值进行操作。

摘要： The various embodiments provide circuitry and methods for packing Log Likelihood Ratio (“LLR”) values into a buffer memory in a compressed format which reduces the amount of buffer memory required. Various embodiments use a type of quantization which reduces the bit width of the LLR values that are stored, with the particular level of quantization depending upon the code rate of the data. The degree, pattern, and periodicity of bit width compression employed may depend upon the code rate of the received transmission. Bit width patterns use for LLR value quantization may be generated by a shift register circuit which provides an efficient mechanism for controlling an LLR packer circuit based upon the code rate of the received signal.
