摘要： Embodiments herein achieve a method and system for selecting non-coherent spreading sequences with binary alphabets {0, 1} with variable spreading factors. The method generates circular shift equivalent sets of spreading sequences by circularly shifting base sequences with elements {1, 0} and having at least one variable spreading factor. The method determines whether each spreading sequence in the circular shift equivalent set meets pre-defined spreading sequence criteria. The spreading sequence criteria comprise balanced criteria, a non- repetition criteria, non-circular criteria, and conjugate criteria. Furthermore, the method selects the spreading sequence from expansions of at least one spreading sequence from the circular shift equivalent sets in response to determining that the spreading sequences in the circular shift equivalent sets meets the pre-defined spreading sequence criteria.

摘要： A receiver receives signals and noise over a frequency spectrum of a desired received signal. The desired received signal is spread using code division multiple access. The received signals and noise are demodulated to produce a demodulated signal. The demodulated signal is despread using a code uncorrelated with a code associated with the desired received signal. A power level of the despread demodulated signal is measured as an estimate of the noise level of the frequency spectrum.

摘要： A subscriber unit for use in a multiple access spread-spectrum communication system includes a spread spectrum radio interface, responsive to a rate function signal from a base station, and first and second despreaders. The base station assigns the rate function spread-spectrum message channels and the first despreader recovers and modifies an information signal one of the spread spectrum message channels. The information channel mode is then modified for processing by the second despreader, with the second despreader supporting a different information signal rate. The subscriber unit has a capability of communicating with a dynamically changing a transmission rate of an information signal which includes multiple spread spectrum message channels. The system includes a closed loop power control system for maintaining a minimum system transmit power level for a radio carrier station and the subscriber units, and system capacity management for maintaining a maximum number of active subscriber units for improved system performance.

摘要： A code-division multiplexing (CDM) system utilized in multi-channel (MC) front-end integrated circuits to significantly reduce the power consumption of such systems. The CDM system extends data compression advantages to uncorrelated and weakly correlated MC signals through the introduction of a new Multi-Channel Signal Binning and Multiplexing (MCSBM) method and architecture. The method achieves significant reductions in power consumption in comparison to a conventional time-division multiplexing quantizer, while adding only a modest amount of overhead and complexity. Systems and methods permit architects to fabricate MC integrated circuits with ultra low power consumption and small chip area. Another embodiment relates to the system's compressor organizing samples of the input signal in such a way that the downstream analog-to-digital converter quantizes the higher variance samples with a higher resolution compared to the resolution it uses to quantize other samples with lower variance.
摘要翻译：在多通道（MC）前端集成电路中使用的码分多路复用（CDM）系统可显着降低这种系统的功耗。 CDM系统通过引入新的多信道信号分组和复用（MCSBM）方法和架构，将数据压缩优势扩展到不相关和弱相关的MC信号。与传统的时分复用量化器相比，该方法实现了功耗的显着降低，同时仅增加了适量的开销和复杂度。系统和方法允许建筑师制造具有超低功耗和小芯片面积的MC集成电路。另一实施例涉及系统的压缩机组合输入信号的样本，使得下游模数转换器与其用于量化具有较低方差的其他样本的分辨率相比，以更高的分辨率量化较高方差样本。
