    Abstract: A method of broadcasting data in a wireless broadcast network, comprising multiplexing data for a wide-area transmission onto a first transmission span, the wide-area transmission being sent from a plurality of transmitters in the network; multiplexing data for a local transmission onto a second transmission span, wherein the multiplexing is onto frequency subbands pseudo-randomly selected from among all usable frequency subbands and the local transmission being sent from a subset of the plurality of transmitters; selecting the first and second transmission spans based on an amount of data to broadcast for the wide-area transmission and an amount of data to broadcast for the local transmission; and broadcasting the local and wide-area transmissions via a wireless link, wherein the data for the wide-area transmission and the data for the local transmission are time division multiplexed (TDM) at each base station, and wherein the first and second transmission spans are first and second time segments, respectively, of a frame of a predetermined time duration as well as a corresponding system.

    Abstract: Techniques are provided to support successive interference cancellation (SIC) receiver processing with selection diversity whereby each of NT transmit antennas may be turned on or off. One symbol stream may be transmitted from each transmit antenna. A SIC receiver recovers the transmitted symbol streams in a specific order. Up to N T ! orderings are evaluated. For each ordering, N T post-detection SNRs are obtained for N T transmit antennas and used to determine N T data rates, where the data rate is zero if the post-detection SNR is worse than a minimum required SNR. An overall data rate is computed for each ordering based on the N T data rates. The ordering with the highest overall data rate is selected for use. Up to N T symbol streams arc processed at the data rates for the selected ordering and transmitted. The transmitted symbol streams are recovered in accordance with the selected ordering.

    Abstract: Se proveen tecnicas para soportar el procesamiento de receptor de cancelacion de interferencia sucesiva (SIC) con diversidad de seleccion en donde cada una de las NT antenas de transmision puede ser encendida o apagada; se puede transmitir una corriente de simbolos desde cada antena de transmision; un receptor SIC recupera las corrientes de simbolos transmitidas en un orden especifico; se evaluan hasta NT! ordenamientos; para cada ordenamiento, se obtienen NT SNR de post-deteccion para NT antenas de transmision y se utilizan para determinar NT velocidades de datos, en donde la velocidad de datos es cero si la SNR de post-deteccion es peor que una SNR minima requerida; se calcula una velocidad de datos global para cada ordenamiento con base en las NT velocidades de datos; se elige para uso el ordenamiento con la velocidad de datos global mas elevada; se procesan hasta NT corrientes de simbolos a las velocidades de datos para el ordenamiento seleccionado y se transmiten; las corrientes de simbolos transmitidas son recuperadas de acuerdo con el ordenamiento seleccionado.

    Abstract: Techniques are provided to support successive interference cancellation (SIC) receiver processing with selection diversity whereby each of NT transmit antennas may be turned on or off. One symbol stream may be transmitted from each transmit antenna. A SIC receiver recovers the transmitted symbol streams in a specific order. Up to NT! orderings are evaluated. For each ordering, NT post-detection SNRs are obtained for NT transmit antennas and used to determine NT data rates, where the data rate is zero if the post-detection SNR is worse than a minimum required SNR. An overall data rate is computed for each ordering based on the NT data rates. The ordering with the highest overall data rate is selected for use. Up to NT symbol streams are processed at the data rates for the selected ordering and transmitted. The transmitted symbol streams are recovered in accordance with the selected ordering.
