20090154392 | CODING BLOCK BASED HARQ COMBINING SCHEME FOR OFDMA SYSTEMS - A method and apparatus for combining retransmitted hybrid automatic repeat-request (HARQ) messages divided into coding blocks in an orthogonal frequency-division multiplexing (OFDM)/orthogonal frequency-division multiple access (OFDMA) receiver are provided. According to such a coding-block-based HARQ combining scheme, the quality of each coding block may be compared to a threshold to determine whether the decoded bits or the HARQ combined signal should be saved for each coding block for subsequent HARQ iterations. In addition to reducing the required HARQ buffer size while preserving the combining gain, coding-block-based HARQ combining may also provide fast decoding and reduced power consumption when compared to conventional HARQ combining techniques. | 06-18-2009 |
20090158109 | SELECTIVE HARQ COMBINING SCHEME FOR OFDM/OFDMA SYSTEMS - A method and apparatus for combining retransmitted hybrid automatic repeat-request (HARQ) messages at different stages in an orthogonal frequency-division multiplexing (OFDM)/orthogonal frequency-division multiple access (OFDMA) receiver are provided. The type of HARQ combiner used for a particular channel may depend on a number of selection criteria including the modulation order of the transmission, the number of bits needed for the combined signals, and the headroom in the HARQ buffer. For some embodiments, a combination of different types of HARQ combiners may be designed into a receiver and selected on a per-channel basis. Proper selection of a HARQ combining scheme may reduce the required HARQ buffer size and may provide an increased combining gain when compared to conventional HARQ combining techniques. | 06-18-2009 |
20090316840 | METHODS AND SYSTEMS FOR STC SIGNAL DECODING USING MIMO DECODER - Space time coding (STC) may be applied at the transmitter adding redundant information in both space and time dimensions. At the receiver, the received STC signal may be decoded using a spatial multiplexing MIMO decoding, for example, based on either Minimum Mean Square Error (MMSE) or maximum-likelihood (ML) algorithms. A selective STC decoder may incorporate both the conventional maximum ratio combining (MRC) decoding scheme and a MIMO decoding scheme. One of the STC decoding schemes may be selected, for example, based on estimated channel conditions in order to achieve a trade-off between error rate performance and computational complexity. Components used for a non-selected scheme may be powered down. | 12-24-2009 |

20140080412 | ADAPTIVE SLICER FOR A DISCRETE LEVEL AMPLITUDE MODULATION RECEIVER - In a wireless communication system, an initiator, such as a card reader, can communicate with a target, such as a smart card or other device emulating a smart card, by amplitude modulating a radio frequency signal. In a receiver, levels of samples of a digital baseband signal of the amplitude modulated signal can vary. Apparatus and methods associate a received sample with a hard or sliced output state (such as +1, 0, or −1) and update a value associated with the hard output state for accurate slicing of the samples. This permits the use of hard symbols in further processing rather than soft samples, which can dramatically reduce the complexity of circuitry. | 03-20-2014 |
