摘要： According to an example embodiment, a method may include allocating, within a single physical resource unit (PRU), a plurality of channel sounding groups. Wherein each channel sounding group includes a frequency-time domain code division multiplexing (CDM) allocation. The method may also include broadcasting, in a downlink direction to one or more mobile stations in a wireless network, a signal that causes the receiving mobile stations to transmit a channel sounding signal. The method may further include receiving at least one channel sounding signal from at least one of the one or more mobile stations, the channel sounding signal being received in an uplink direction via one or more channel sounding groups. And, the method may include estimating the channel quality, of the channel used by the physical resource unit, based upon the received at least one channel sounding signal.

摘要： Method and apparatus for soft bit computation with a reduced state equalizer. The method assures that the number of states in the equalizer is reduced to obtain acceptable complexity, while also ensuring that soft bit computation is performed for substantially all bits. The method involves computing a first set of soft bits from bits transmitted in a received signal, using a reduced-state trellis with finite non-zero delay, calculating hard decisions in response to the received signal, and also ensuring that substantially all soft bits are computed by employing zero-delay soft decision-making or decision-feedback equalization to compute a second set of soft bits. Furthermore, the hard decisions are used to compute the second set.

摘要： In a receiver first stage, received signals are equalized using first stage channel estimates, a first data stream is separated from a second data stream; and interference on the first data stream is re-generated by filtering the decoded first data stream (after decoding) using the first stage channel estimates. Second stage channel estimates are calculated using the first stage channel estimates and gain derived from generating the interference, and the interference is subtracted from the received signals. In the receiver second stage, the signals from which the interference was subtracted are equalized using the second stage channel estimates, the second stream of data is decoded; and the decoded first data stream and the decoded second data stream are output. One embodiment gets channel estimates for each stage from the received signal and regenerates pilot interference; the other calculates updated channel estimates from the first stage for use in the second stage.
