Baseband Engineer Lake Forrest, CA Full Time

Job Description

Company is looking to fill the position
of principal scientist in the Baseband Demodulator VLSI/Group.  Company is a fabless semiconductor company developing integrated circuits (ICs) for the developing mobile television market, specifically addressing mobile audio and video standards such as DVB-H, ISDB-T, T-DMB, and DAB.
  The Company has assembled a world-class team of engineers with expertise in radio frequency (RF) systems and circuit design, phase locked loops (PLLs), analog-to-digital converters, digital communication systems, digital signal processing, very large scale integrated (VLSI) circuits, low power logic and circuit design, and system-on-a-chip (SOC) design.  The Baseband Demodulator VLSI/Systems Group currently consists of 15 engineers, with over half of these engineers holding Ph.D. degrees in engineering disciplines related to IC design. 

The job description for this open position has two components. 

The first component is to research and specify advanced communications systems for mobile receivers.  This requires an understanding of demodulation algorithms for orthogonal frequency division multiplexing (OFDM) signals, expertise in advanced digital signal processing (DSP) and digital communication principles such as digital filtering, digital timing and carrier recovery, channel estimation, and equalization.  Deep understanding of forward error correction (FEC) techniques is required, including Galois field theory, Reed-Solomon codes, convolutional codes, Turbo codes, and combinations of these such as concatenated codes and product codes. Experience in efficient implementation of FEC decoders such as Viterbi, Reed Solomon, and Turbo decoders is required.  

The second component is to research and develop an ASIC implementation of the specified system which is energy efficient and has a small silicon footprint.  Energy efficiency is required due to the battery powered nature of mobile devices, and an energy efficient implementation requires the use of state of the art design techniques such as voltage scaling, power islands, and clock gating, and development of VLSI architectures designed to reduce dynamic switching power.  A small silicon footprint is required due to the cost sensitivity and small form factor of mobile devices, and this requires area efficient VLSI architectures along with a solid understanding of the system so the proper balance can be struck between silicon area and system performance. 

Based on the breadth and depth of expertise required for this position, it is expected that the successful candidate will have a Ph.D. in Electrical Engineering or a related discipline along with at least 5 years of relevant experience
