摘要： A digital baseband (DBB) radio frequency (RF) receiver includes a digital high pass filter compensation (HPFC) module used to suppress group delay variation distortion caused by using low cost analog high pass filters (HPFs) in the receiver. The digital HPFC module reduces a cutoff frequency, established by the HPFs for the real and imaginary signal component frequency domain responses by providing a first compensation signal having a first predetermined value (K 1 ). The digital HPFC module adjusts the gain of the high pass response of the real and imaginary signal component frequency domains by providing a second compensation signal having a second predetermined value (K 2 ).

摘要： A method and apparatus are described that provides flexible spectrum usage by using a paired frequency division duplex (FDD) spectrum to enable dynamic access in television white space (TVWS), sub-leased spectrum or unlicensed spectrum, (e.g., industrial, scientific and medical (ISM) bands), in a femto cell environment or the like. Elastic FDD (E-FDD) enables femto cell operation in TVWS, sub-leased spectrum and/or unlicensed spectrum, either simultaneously with licensed spectrum or as an alternate channel to licensed spectrum. E-FDD enables dynamic asymmetric bandwidth allocation for uplink (UL) and downlink (DL) in FDD, and enables variable duplex spacing, (i.e., using FDD with minimum duplex spacing between DL and UL spectrum, or, using hybrid-FDD, (FDD in a time duplexed fashion), when a spectrum gap between the UL and DL spectrum is below a certain minimum threshold. Additionally, the signaling enhancements to implement E-FDD are also provided.
摘要翻译：描述了一种方法和装置，其通过使用成对的频分双工（FDD）频谱来实现灵活的频谱使用，以实现电视空白（TVWS），次租用频谱或非许可频谱（例如工业，科学和医学）（ISM）频带），在毫微微小区环境等中。弹性FDD（E-FDD）使得能够在TVWS，子租用频谱和/或非许可频谱中的毫微微小区操作，或者与许可频谱同时或作为许可频谱的备用信道。 E-FDD实现了FDD中的上行链路（UL）和下行链路（DL）的动态非对称带宽分配，并且实现了可变双工间隔（即，使用DL和UL频谱之间具有最小双工间隔的FDD，或者使用混合FDD， FDD以时间双工方式），当UL和DL频谱之间的频谱间隔低于某个最小阈值时，还提供了实现E-FDD的信令增强。

摘要： A communication system (100) including an automatic control (AGC) circuit (105), a receiver (110), an analog to digital (ADC) converter (115) and an insertion phase variation compensation module (120). The AGC circuit receives and amplifies communication signals (150). The gain of the AGC circuit is adjusted. The AGC circuit outputsan amplified signal (145) to the receiver which, in turn, outputs an analog complex signal to the ADC (115). The ADC outputs a digital complex signal to the insertion phase variation compensation module (120) which counteracts the effects of phase offsets introduced into the communication signal due to the continuous gain adjustments associated with the AGC circuit.

摘要： The present invention relates to secret key generation and authentication methods that are based on joint randomness not shared by others (JRNSO), in which unique channel response between two communication terminals generates a secret key. Multiple network access points use a unique physical location of a receiving station to increase user data security. High data rate communication data is encrypted by generating a random key and a pseudo-random bit stream. A configurable interleaving is achieved by introduction of JRNSO bits to an encoder used for error-correction codes. Databases of user data are also protected by JRNSO-based key mechanisms. Additional random qualities are induced on the joint channel using MIMO eigen-beamforming, antenna array deflection, polarization selection, pattern deformation, and path selection by beamforming or time correlation. Gesturing induces randomness according to uniquely random patterns of a human user's arm movements inflected to the user device.
