Publication number: 20120170475Abstract: A system and method for optimal allocation of bandwidth in a multichannel transmission channel. In an embodiment, a system may allocate a specific amount of bandwidth in the transmission channel in order to maximize the value of the data that is transmitted on a per-channel basis. Typically, a transmission channel has enough bandwidth to accommodate the minimum bandwidth for all data across all channels. The excess bandwidth may be allocated in an optimal manner so as to provide additional bandwidth for the most valuable channels. The maximum allocation of bandwidth is a point in which allocating additional bandwidth to a channel does not yield any additional value. Such an allocation may be accomplished using an iterative analysis of the available bandwidth and a microeconomic-based analysis of the subjective value of each channel.Type: ApplicationFiled: January 26, 2011Publication date: July 5, 2012Applicant: STMicroelectronics, Inc.Inventor: Steven SREBRANIG

Publication number: 20120170691Abstract: Interference cancellation for wideband and narrowband communications systems is provided without apriori knowledge of statistical information about an interfering signal. In one embodiment a demodulator circuit can operate in an environment where a “no lock” situation would normally occur to remove the interference and acquire signals in low signal-to-noise ratio (SNR) conditions and high signal-to-interference ration (SIR) conditions. In other embodiments, performance is improved by introducing statistics of the interfering signal, and these statistics regarding the communications channel and interference properties (i.e., characteristics of the interfering signal) can be adaptive or “learned” in other embodiments.Type: ApplicationFiled: November 16, 2011Publication date: July 5, 2012Applicant: STMICROELECTRONICS (CANADA), INC.Inventors: JOSE AUGUSTO LIMA, ANTONIO MASCIOLI

Publication number: 20120169376Abstract: Disclosed is a deglitcher circuit having a programmable hysteresis. The deglitcher samples a received input signal, wherein the input signal may include one or more glitches. Responsive to a change in state of the sampled input signal, the deglitcher counts the number of samples of the changed state of the input signal. The count value increments with each sampled changed state, and decrements with each sampled original state of the input signal. When the count value reaches a threshold, the state of the output signal is changed. The output signal of the disclosed deglitcher circuit provides an accurate, glitch-free reconstruction of the sampled input signal. Additionally, the disclosed deglitcher circuit reduces the number of memory elements required for a given number of samples of the input signal, thereby allowing for a larger number of samples to be taken without necessarily having to increase the memory elements required by the deglitcher.Type: ApplicationFiled: December 29, 2010Publication date: July 5, 2012Applicant: STMicroelectronics, Inc.Inventor: Vincent Himpe
