The present invention provides novel methods for reducing the complexity of preferably a genomic sample for further analysis such as direct DNA sequencing, resequencing or SNP calling. The methods use pre-selected immobilized oligonucleotide probes to capture target nucleic acid molecules from a sample containing denatured, fragmented (genomic) nucleic acids for reducing the genetic complexity of the original population of nucleic acid molecules.

A method of assigning downlink time slots to receive units where the units may generate data using different modulation schemes. The method preferably assigns the downlink time slots as a function of the complexity of modulation schemes employed by the units. Further, the method preferably assigns the time slots from the least complex modulation scheme to the most complex scheme. The method may further assign uplink time slots to transmit units where the transmit units may generate data using different modulation schemes. The method preferably assigns the uplink time slots as a function of the complexity of modulation schemes employed by the uplink units. Further, the method preferably assigns the uplink time slots from the least complex modulation scheme to the most complex scheme. In other embodiments, the downlink time slots are assigned as a function of the bit per symbol rate employed by the receive units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate. Further, the uplink time slots are assigned as a function of the bit per symbol rate employed by the transmit units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate. The present invention is also a method of simplifying the encoding of a predetermined number of bits of data into frames. The method adds error coding bits so that a ratio of the frame length times the baud rate of the frame times the bit packing ratio of the data divided the total bits of data is always an integer. The method may also convolutionally encode the bits of data so that the same equation is also always an integer. The present invention is also a method of updating the weights of a FIR filter where the filter processes symbols having variable modulation rates. When the modulation rate of the incoming symbols changes, the weights corresponding to the first symbol having the new modulation rate are changed based as the symbol propagates through the filter.

A modem is provided for receiving the digital signal in the first format. A digitizer is also provided for receiving the analog signal from the telephone. The system, in a first mode of operation, couples the digital signal in the first format to the modem, and in a second mode of operation, couples the analog signal from the telephone to the digitizer. The second mode of operation may be, for example, a power failure mode of operation.

Embodiments of the invention may provide systems and methods for detecting the presence a DTV signal such as an ATSC DTV signal. The system and methods may be applied to a received RF signal that has been down-converted to a baseband or low-IF digitized signal. The systems and methods may detect a presence of a DTV signal by searching for its characteristic pilot signal, known to reside in a fixed frequency range for all valid DTV signals. This pilot signal may be extracted by processing the baseband or low-IF signal in multiple stages. The first stage may reduce the signal information to that pertaining to the frequency band covering all valid pilot frequencies and commensurately reduces the sampling rate, and hence computational complexity of subsequent operations. A second stage may then efficiently operate on this reduced rate signal to focus on a series of particular pilot frequencies for interrogation. For each such candidate frequency, the cyclostationarity of the signal may be measured and tested for statistical significance relative to the background energy to yield an effective test that is invariant with respect to the background noise level. In a simplified case, this can correspond to measuring the energy in a very tight candidate subband normalized against the energy from a larger subband. Furthermore, the energy in the candidate subband can be taken as the energy in a Fourier series coefficient.

A device for performing channel estimation in an OFDM system includes a non-volatile memory, a G matrix selector and a channel estimate generator. The non-volatile memory stores a set of G matrices indexed by signal to noise ratio, the G matrices being precalculated for a plurality of signal to noise ratios using a fixed Doppler frequency and a fixed delay spread. The G matrix selector uses a quantised signal to noise ratio to select a G matrix from the set of G matrices stored in the non-volatile memory. The channel estimate generator multiplies the selected G matrix by LS estimates for the reference signal to obtain a channel estimation.
