A system includes a memory, a processor, and an accelerator circuit. The accelerator circuit includes an internal memory, an input circuit block, a filter circuit block, a post-processing circuit block, and an output circuit block to concurrently perform tasks of a neural network application assigned to the accelerator circuit by the processor.

The multi-band antenna structure includes a first antenna having a band width about a middle frequency and a second antenna spaced and electrically isolated from the antenna. Ends of the second antenna are shorted to each other and the antenna floats electrically. The first and second antennas are planar and superimposed in parallel planes. At least two layers of dielectric material of a thickness is between the two antennas. A third layer of dielectric material of a third thickness is between the two antennas.

A scalar Kalman filter is applied for a Least-Square estimated value Hat s. The filter has an input for receiving H, a filter equation and an out for the corrected estimated value Hfor the kvariable. The filter equation is H=KS[k] wherein: correction S[k]=S+K(H&#x2212;S); prediction of the correction S=KS[k]; Kalman filter gain K=P/(1+P); minimum predication MSE P=KP[k]+K; minimum MSE P[k]=P (1&#x2212;K); and K, Kand Kare constants.

An analog TV receiver implementation on DSP allows mobile platforms to view analog TV broadcasting on LCD displays. The analog television receiver includes a demodulator for demodulating a received analog television signal, an analog to digital converter for digitizing the demodulated television signal and a digital signal processor for producing display signals from the digitized television signals. The digital signal processor being programmed to search for a horizontal synchronization signal in the television signal, track the horizontal synchronization signal and search for a vertical synchronization signal in the television signal. Next the processor separates a luminance and a pair of chrominance components of the television signal and demodulates the pair of chrominance components. Red, green and blue values are constructed from the demodulated chrominance components and the luminance components. Display signals are produced from the red, green and blue values.

Digital implementation of analog TV receiver

A method and apparatus for decoding a coded data stream of bits using an inner decoder, deinterleaver and an outer decoder. The outer decoder first decodes by error correction decoding for r errors per word. The decoding is terminated and a decoded word is outputted if the syndromes of the corrected word of the first decoding are all zeros. If the syndromes of the corrected word of the first decoding are not all zeros, a second decoding is performed by error decoding and erasure for the number of errors reduced by one and the number of erasures increased to two. The decoding is terminated and a decoded word is outputted if the syndromes of the corrected word of the second decoding are all zeros. If the syndromes of the corrected word of the second decoding are not all zeros, the second decoding by correcting and erasure decoding is repeated for the number of errors reduced by one and the number of erasures increased by two for each iteration of the second decoding.

A receiver for orthogonal frequency division multiplexing signals, including art A/D converter for converting receiver analog signals to a digital signal data stream, wherein the digital signal data stream includes symbols separated by guard segments. The receiver also includes an I/Q demodulator for producing a first set of complex I and Q components from the digital signal data stream and a guard segment length detector using the first set of I and Q components. It further includes an extractor for identifying and removing the guard segments of the detected length from the digital signal data stream and an FFT demodulator for demodulating the symbols of the digital signal data stream to produce second sets of complex I and Q components.

Receiver with signal offset estimator and symbol synchronizing generator

A receiver includes a controller which receives A/D sampled input signals and shifts the sampled digital signal to compensate for Doppler effect in the input signal prior to demodulation. The controller compensates for a Doppler increased frequency by shifting the sampled digital signal so as to skip a sample period every n samples. This may be achieved by decreasing a cycle of m samples by one sample period every n samples. The controller compensates for a Doppler decreased frequency by shifting the sampled digital signal so as to add a sample period every n samples. This may be achieved by repeating a sample every n samples to shift the sampled digital signal. The compensation is performed in software on a multi-threaded processor.
