摘要： In a multipoint data communication system using quadrature-amplitude modulation, a master modem (20) and a plurality of tributary modems (11a, 11b . . . 11n) are interconnected via respective transmission channels (13a, 13b . . . 13n, 16). Adaptive equalizer circuitry (55, 56) in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from the tributary by an ensemble of tap coefficients associated with the tributary. The tap coefficient ensembles for each tributary are stored in a memory (91) from which they are retrieved at the start of transmission from that tributary. Timing-acquisition circuitry (29) within the master modem adjusts the phase of the latter's sampling circuitry (23, 27) at the start of transmission from a given tributary so that the received signals are sampled at the correct time points. In particular, a timing acquisition signal having spectral components only within the non-rolloff region of the equalized baseband-equivalent transfer function is transmitted by the tributary. The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisiton equalizer outputs. The time by which the operation of the sampling circuitry is to be advanced or retarded is determined as a trigonometric function of two successive ones of the timing acquisition equalizer outputs. The timing acquisition signal is illustratively a double-dotting pattern having a four-symbol-interval period. That period is integrally related to the carrier frequency. This allows the samples needed in order to begin forming the timing acquisition equalizer outputs to be generated by replicating the samples taken over only four symbol intervals.

摘要： Slotted Aloha-NOMA (SAN) protocol is an uncoordinated, non-orthogonal, random access protocol that exploits the simplicity of SA (Slotted Aloha) and the superior throughput of non-orthogonal multiple access (NOMA) and its ability to resolve collisions via use of successive interference cancellation (SIC) receiver. In SAN protocol, the SIC receiver at the IoT gateway adaptively learns the number of active devices (which is not known a priori) using multiple hypothesis testing in order to successfully distinguish between signals transmitted from different IoT devices.

摘要： Method and apparatus for transmitting messages in a two-way paging system are disclosed. Reply codes corresponding to portions of a message to be transmitted by a base station and received by a mobile pager device are computed either at the base station or at the pager according to various embodiments. The reply codes, which are typically shorter and require less bandwidth than the full text to which they correspond, are incorporated by the pager into reply messages when the user of the pager device wishes to refer to portions of the text of the received message in his reply. The present invention advantageously allows the user of a pager device to respond to a received message by transmitting a reply message that incorporates part of the text of the original received message without significantly increasing the bandwidth required to transmit the response.

摘要： Improved image quality is realized in a parallax-free teleconferencing display by increasing the camera light budget, that is, by increasing the light available to the camera, while maintaining a common optic axis between the camera and the display screen. Light-attenuating devices, such as color filters, are repositioned out of the path of light entering the camera. In this manner, image quality is improved while color capability is maintained.

摘要： A receiver includes an interference canceller circuit which receives a corrupted signal and makes an estimate of the desired signal. Subsequently, an estimate of the interference signal is determined by subtracting the estimated desired signal from a delayed version of the received signal. The receiver forms a final estimate of the desired signal by subtracting the estimated interference from a second delayed version of the received signal.
