    摘要： Quasi-parallel read/write interleaver architecture for data blocks by sequential spreading of variable size data subblocks into memory banks with bank address contention initiating the next data subblock. Iterative Turbo decoders with MAP decoders use such quasi-parallel interleavers and deinterleavers.

    摘要： Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.

    摘要： A communication circuit (28) is designed with a signal processing circuit (370) arranged to produce a first plurality of data signals and receive a second plurality of data signals. A transmit circuit (364) is coupled to receive the first plurality of data signals and transmit each data signal of the first plurality of data signals on a respective transmit frequency in a predetermined sequence of transmit frequencies. A receive circuit (362) is coupled to receive each data signal of the second plurality of data signals from a remote transmitter on the respective transmit frequency in the predetermined sequence. The receive circuit applies the second plurality of data signals to the signal processing circuit.
