PROFESSIONAL EXPERIENCE:

Confidential

Responsibilities:

• Studied and analysed the Lync Architecture and its deployment types viz.
• Simulated the voice routing in Lync from the origin of a call, routing & authorization procedures & its connection to the end user.
• Built a system that checked for dialling behaviour and authorization of a number dialled by the user which went through normalization techniques, reverse number lookup, voice & location policy, usages and trunk configuration/number translation.
• Also, studied about the voice policies, location based routing & least cost based routing, RGS and IVR .

Confidential

Responsibilities:

• Performed 2-PSK modulation scheme for transmission and reception of data.
• Implemented Zero forcing (ZF) linear equalizer and linear minimum mean-square error equalizer (LMMSE)
• Estimated Performance factor such as Symbol Error Rate (SER) based on channel taps and number of symbols transmitted.

Confidential

Responsibilities:

• Simulated a Rician wireless channel ( RF circuit ) using Viterbi Encoder/Decoder and Space Time Block Code to transmit a QPSK modulated signal.
• Decoded the multipath waves at the receiver with randomly distributed amplitudes and phases combined.
• Used block phase estimation and phase compensation and maintained the Bit Error Rate (BER) close to zero.
• Analysed that Puncturing scheme increases coding rate and Block Interleaver corrects burst errors occurring in noisy environments.

Confidential

Associate Procurement Engineer

Responsibilities:

• Implemented the functionality of standard "Ping" program with UDP instead of ICMP .
• Calculated the RTT (Round Trip Delay) of each packet when the server responds using Python.

Confidential

Responsibilities:

• Captured & analyzed network traffic while establishing a connection between computer and the Internet to run a Confidential video.
• Observed captured data packets, message size, window size, group of transmission errors along with various protocols like ARP, RIP, RIPv2, EIGRP, OSPF, BGP, DHCP, DNS, ICMP, HTTP etc.
• Traced route from source node to destination node and noted the port number for the flow.

Confidential

Responsibilities:

• Built a system by trouble shooting and debugging, to capture, measure and generate various analog and digital signals (Sinusoidal, Square, Sawtooth etc.) with a voltage range of +/- 5V with frequencies up to 450 kHz using an ARM M4F core (TM4C123GH6PMI microcontroller) .
• It also involved PCB designing, layout and fabrication .
