Data communication devices, methods, and systems

摘要

Data communication devices, methods, and systems are discussed in this application. In one embodiment, a receiving apparatus generally comprises a detector, an indicator, and a decision device. The detector can detect a number of data streams contained in a signal received on a single physical channel. Detection can be made by comparing a received signal with one or more predetermined sequences and identifying one or more of the plural predetermined sequences as being likely contained within the received signal. Each data stream can be associated with at least one predetermined sequences. The indicator can provide an indication of the data streams likely contained in the signal based on the identified sequences. A decision device can provide data defining a receiver configuration based on the indication, the receiver configuration being suitable for configuring a decoder to decode only the one or more data streams indicated as being likely contained in the signal. Other aspects, embodiments, and features are also claimed and discussed.

主权项

1. A receiving apparatus for detecting data streams in a communication system, the receiving apparatus comprising:
a detecting apparatus comprising:
a detector configured to detect, prior to initiating a decoding process, a number of data streams contained within a signal received on a single physical channel by comparing the received signal with plural predetermined sequences and identifying one or more of the plural predetermined sequences as being likely contained within the received signal, each data stream being associated with one of the plural predetermined sequences, at least one of the predetermined sequences being based on a training sequence assigned to a mobile station during registration of the mobile station in a network; andan indicator coupled to the detector and configured to provide an indication of the data streams likely contained in the received signal based on the identifying; and a decision device coupled to the detecting apparatus and configured to provide data defining a receiver configuration based on the indication, the receiver configuration being suitable for configuring a decoder to decode only the one or more data streams indicated as being likely contained in the received signal.
