摘要： Method and apparatus for generating random numbers are disclosed. In one aspect, a method for generating random numbers for use in a wireless communication device provides for generating random numbers, gathering a sample of the generated random numbers, and computing at least one metric, such as mean value, standard deviation, and/or entropy. The method further provides for comparing the metric with a corresponding reference value and adjusting the metric based on a result of said comparison so that the generated random numbers achieve a desired distribution. In another aspect, an apparatus for generating random numbers includes an analog noise generator and hardware components for generating random numbers and feedback values to adjust the random numbers. The apparatus further includes a processor capable of executing instructions to carry out control algorithms for adjusting the random numbers.

摘要： At least one feature provides a way to perform point-to-multipoint transmissions using adaptive or directional antennas while reducing antenna pattern distortion. Generally, rather than transmitting the same waveform to two or more receivers, an information-bearing signal is transformed into different decorrelated waveforms and each decorrelated waveform is transmitted to a different receiver. In one implementation, an information-bearing signal is transformed into two decorrelated signals such that their crosscorrelation, or autocorrelation of the information-bearing signal, is zero or very small. Such decorrelation may be achieved by sending a first signal to a first receiver while sending a second signal, having a radio frequency spectrum that is the spectrally inverted version of the first signal, to a second receiver. In another implementation, a first signal is transmitted to a first receiver and is also transmitted to a second receiver with a time delay.

摘要： A desired information stream is recovered from a pair of independent bitstreams transmitted using quadrature modulation. One of the independent bitstreams is altered by an invertible alteration function prior to transmission. The quadrature modulated bitstreams are demodulated at a receiver to provide a demodulated I bitstream and a demodulated Q bitstream. One of the demodulated I and Q bitstreams is tentatively provided for decoding. The tentatively provided bitstream can be optionally inverted. One of the tentatively provided bitstream and the optionally inverted bitstream is decoded if it is desired to recover the bitstream that was not altered by the alteration function prior to transmission. One of the tentatively provided bitstream and the optionally inverted bitstream is decoded after applying the inverse of the alteration function thereto if it is desired to recover the bitstream that was altered by the alteration function prior to transmission. An error rate of data decoded during the decoding step is determined. If the error rate is not acceptable, different choices of the demodulated I and Q bitstreams with and without inversion are tried until an acceptable error rate is obtained.
