Abstract

LTE-A (Long Term Evolution-Advanced) is the fourth generation technology to increase the speed of wireless data network. The LTE-A Physical layer provides both data and control information between an enhanced base station and mobile user equipment which is quite complex and consists of a mixture of technologies. Since there is requirement for more resources to accommodate all the channels in a single FPGA, Partial Reconfiguration (PR) technique is introduced to configure the total hardware into sub modules that configure and operate in different instants of time. PR enables a part of FPGA to be reconfigured, while the rest continues to function without any interruptions and reduces the hardware resource power and fabric area. This work proposes the realization of transmitter and receiver architecture of Physical Hybrid Indicator Channel (PHICH) channel for LTE-A using partial reconfiguration on xc6vlx240tff1156-1 FPGA. The receiver architecture for PHICH is to report the correct reception of uplink user data to the User Equipment (UE) in the form of Acknowledgment (ACK), or Negative ACK (NACK) in a 1 millisecond duration sub-frame of Long Term Evolution (LTE) System. The modules for the different diversities are reconfigured based on the control signals from the transmitter.

Abstract

The CDIO INITIATIVE is an innovative educational framework that has been followed in many world-class educational institutions in USA, Europe and Asian countries for producing the next generation of engineers. It provides students with an education in the context of Conceiving — Designing — Implementing — Operating (CDIO) real-world systems and products. Thiagarajar College of Engineering (TCE), Madurai is one among those institutions following the CDIO framework for all undergraduate engineering programmes since the academic year 2018-19. Though there are training programs for selective faculty members, there had been no intensive hands - on training to all the faculty members. It has been felt from the formal meetings and informal discussions that faculty members needed more clarity and training on the CDIO framework. This has led to the conduct of training workshops online by the TCE academic process team for the faculty members of the institution (n=205), in three batches. Two quizzes have been conducted and feedback has been collected at the end of the workshop for each batch. This research paper analyses the outcome of these workshops measured through the Higher Order Thinking Skills (HOTS) exhibited in the assessment activities and feedback. It has been observed that the training workshop satisfies the expectations of the participants with a Satisfaction Index of 0.924. Recommendations have been proposed for interpreting the outcomes of such training workshops to enhance faculty competence through such workshops by addressing the necessary gaps in the forthcoming training workshops.
