摘要： A method and apparatus for compression of complex data signals within a telecommunications base station. The method includes representing a sample of a complex value discrete time signal using 2(L−N)−S mantissa bits and 2N+S exponent bits to realize peak output signal to noise ratios over a wider dynamic range compared to a conventional L-bit uniform quantization format. The increases in dynamic range and peak output SNR is achieved without increasing the average number of data bits per sample and with relatively simple computational effort.

摘要： A fluorescent bulb compactor and mercury vapor recovery system that allows for the safe collection and disposal of crushed or broken fluorescent lamps, while recovering substantially 100% of the hazardous mercury vapors contained within the lamps. A fluorescent lamp is inserted within a drum and broken into fragments by one or more blades, with the fragment falling to the bottom of the drum. The mercury vapors that are emitted from the broken fluorescent lamps are forced out of the drum by negative positive pressure created by a vacuum/filter assembly. Once through the filter assembly, which includes a HEPA filter and activated carbon filter, the gases are permitted to escape into the environment virtually 100% free of mercury toxins.

摘要： A system and method are provided for frequency domain peak power reduction on a plurality of orthogonal frequency divisional multiplexing (OFDM) signals in a communications system, wherein frequency domain processing of at least one OFDM signal carrier is iteratively performed to reduce peak power transmissions. OFDM signal carriers can include both in-band sub-carrier signals, and guard-band sub-carrier signals. Each iteration of peak power reduction takes as an input the frequency domain representation of the signal from the previous iteration that has been altered with respect to an error signal also represented in the frequency domain, determines an error signal (in the frequency domain), and subtracts this from the input to produce a further peak power reduced frequency domain signal. If there are no peaks above the configured peak power reduction threshold, then the signal passes through the FPPR iterations with no change.
摘要翻译：提供了一种在通信系统中的多个正交频分复用（OFDM）信号上进行频域峰值功率降低的系统和方法，其中迭代地执行至少一个OFDM信号载波的频域处理以减少峰值功率传输。 OFDM信号载波可以包括带内子载波信号和保护带子载波信号。峰值功率降低的每次迭代将来自先前迭代的信号的频域表示作为输入，其相对于也在频域中表示的误差信号已被改变，确定误差信号（在频域中），以及从输入中减去此值，以产生另一个峰值功率降低的频域信号。如果在配置的峰值功率降低阈值以上没有峰值，则信号通过FPPR迭代而没有变化。

摘要： Antenna systems are used for transmitting common overhead channels (pilot, sync, and paging channels) over a whole sector while transmitting and receiving unique traffic channels on individual beams in the sector. Each beam in the sector is transmitted at a frequency offset from other beams in the sector. The offset frequency is chosen such that the effect of cancellation of the pilot channel caused by the summing of signals from multiple beams is minimized. Alternative, each beam in the sector can have a time dependent phase offset relative to each other to minimize the effect of cancellation of the pilot channel caused by the summing of signals from multiple beams. System capacity is substantially increased since the number of traffic carrying beams per sector is increased without using more pilot channel PN offsets. Beams are fixed and the same antennas are used for the overhead channels as the traffic channels, obviating the need for complex algorithms and calibration procedures.

摘要： Peak power reduction in transmit chains of frequency hopping, multi-band radiocommunication devices is performed. Filtering and, optionally, interpolation of a signal being processed for peak power reduction can be performed only in an error signal path or in both an error signal path and a primary signal path. Alternatively, a sufficiently high sample rate can be used in support of error signal generation.

摘要： An access probe existing and generated within a base station to simulate a mobile terminal for the purpose of testing base station receive functionality within a communications system. The access probe data is injected at baseband rather than at RF to eliminate the need for analog/RF circuitry. The access probe performs injection at the front end of the base station receiver to exercise as much receive data path as possible. A unique ID is embedded in the access probes so that the communications system is aware which probes within a sequence were received successfully and at what power level. Within in-field applications, the unique ID allows the communications system to distinguish simulated access probes from those corresponding to real mobiles.

摘要： A method and system for wireless communication channel estimation. A frequency offset hypothesis is determined. An interchannel interference (“ICI”) matrix based on the frequency offset hypothesis is generated. Pilot channel estimates based on the ICI matrix are obtained. A correlation error of the pilot channel estimates to the frequency offset hypothesis is calculated. The correlation error is compared with a predetermined correlation error value. The frequency offset hypothesis is updated and the aforementioned steps are iteratively repeated if the correlation error is greater than the predetermined correlation error value. The pilot channel estimates are used to estimate the wireless communication channel.
