US09118367B2 Wideband power efficient high transmission power radio frequency (RF) transmitter
Embodiments provide transmitter topologies that improve the power efficiency and bandwidth of RF transmitters for high transmission power applications. In an embodiment, the common-emitter/source PA of conventional topologies is replaced with a current-input common-base/gate PA, which is stacked on top on an open-collector/drain current-output transmitter. The common-base/gate PA protects the output of the transmitter from large output voltage swings. The low input impedance of the common-base/gate PA makes the PA less susceptible to frequency roll-off, even in the presence of large parasitic capacitance produced by the transmitter. At the same time, the low input impedance of the common-base/gate PA reduces the voltage swing at the transmitter output and prevents the transmitter output from being compressed or modulated. In an embodiment, the DC output current of the transmitter is reused to bias the PA, which results in power savings compared to conventional transmitter topologies.

In a DTV transmitter the bits of shortened BCH codewords that exhibit undesirably low densities of ONEs are ONEs' complemented before being further coded, and used to modulate carrier waves.

US09118350B2 Methods, apparatus, and systems for coding with constrained interleaving
Serially-concatenated codes are formed in accordance with the present invention using a constrained interleaver. The constrained interleaver cause the minimum distance of the serial concatenated code to increase above the minimum distance of the inner code alone by adding a constraint that forces some or all of the distance of the outer code onto the serially-concatenated code. This allows the serially-concatenated code to be jointly optimized in terms of both minimum distance and error coefficient to provide significant performance advantages. Constrained interleaving can be summarized in that it: 1) uses an outer code that is a block code or a non-recursive convolutional code, and as such, there are multiple codewords present in the constrained interleaver, 2) selects a desired MHD, 3) selects an interleaver size and a set of predefined interleaver constraints to prevent undesired (low-distance) error events so as to achieve the desired MHD, and 4) performs uniform interleaving among the allowable (non-constrained) positions, to thereby maximize or otherwise improve the interleaver gain subject to the constraints imposed to maintain the desired MHD.

US09118346B2 Complementary switches in current switching digital to analog converters
The present disclosure provides embodiments of an improved current steering switching element for use in a digital to analog (DAC) converter. Typically, each current steering switching element in the DAC converter provides a varying set of currents for converting a digital input signal. Generally, the switches and drivers in the current steering switching elements are scaled down proportionally to the current being provided by the current steering switching element according to a ratio as less and less current is being driven by the switching element in order to overcome timing errors. However, device sizes are limited by the production process. When a switch is not scaled proportionally to the current, settling timing errors are present and affects the performance of the DAC. The improved current steering switching element alleviates this issue of timing errors by replacing the single switch with two complementary current steering switches.
