Abstract: A method and apparatus for providing auxiliary data in a idle portion of a slot in a time division multiple access system are disclosed. A speech coder converts speech into digital signals that are coupled to a convolutional coder. The convolutional coder processes the digital signals using three or four connection polynomials to create two sets of outputs. One set of outputs, which is generated from first and second connection polynomials is identical to the standard output of a IS-136 convolutional coder. The second set of outputs, which are the auxiliary data, is generated using third and fourth connection polynomials. The second set of outputs is coupled to a puncturing function, which appropriately deletes portions of the second set of outputs. The remaining portion of the second set of outputs is transmitted in the idle portion of a time slot.

Abstract: A binary design criteria for PSK-modulated space-time codes is provided. For linear binary PSK(BPSK) codes and quadrature PSK (QPSK) codes the "binary rank criterion" (i.e. the binary projections of the unmodulated code word, as binary matrices over the binary field) is used as a design criterion. Fundamental code constructions for both quasi-static and time-varying channels are provided.

Abstract: A satellite data receiver, a satellite data receiver controller, a method, an article of manufacture, and a propagated signal, which process polarization information from another satellite data receiver in order to permit multiple types of signals to be received by a conventional outdoor unit of a satellite reception system. The satellite data receiver, satellite data receiver controller, method, article of manufacture, and propagated signal also utilize decoding techniques to ensure no data is lost during a polarization switch. The satellite data receiver, satellite data receiver controller, method, article of manufacture, and propagated signal provide upgraded service without upgrading the outdoor unit and without requiring an installer to enter the consumer's home.
