Turbo Decoders

Turbo coding is a channel coding technique that increases the capacity of communications systems, especially wireless and mobile. Due to its high correction capability, this technique is used in modern wireless communication standards such as 3GPP and LTE/LTE-Advanced. One of the features of these systems is the increase in data processing capacity, where transmission rates of up to 1 Gbps are specified. However, the turbo coding technique inherently presents a limited performance as a consequence of the turbo decoding process at the reception stage. The turbo decoder presents a high operation latency mainly caused by the iterative decoding process, the interleaver and deinterleaver stage and the estimation process of the information bits. In this work, we show the techniques used to implement modern low-latency turbo decoders suitable for 3G and 4G standards.

In this paper, a 3.5 GHz CMOS sub-harmonic mixer for LTE-advanced applications is presented. The mixer with the bulk-controlled technique improves the linearity and mitigates the power of the local oscillator. The proposed mixer is implemented by tsmc 0.18 μm Mixed Signal RF CMOS 1P6M process and consumes 2.2 mA from a 1.2 V supply. The proposed mixer operates at 3.5GHz LTE-advanced bands and achieves maximum input third-order intercept point (IIP3) of 2.3dBm, power conversion gains of 1.3 dB.

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.
