Signal Processing Engineer

Role Overview: As a Physical Layer/Baseband Processing Engineer at 7 Darter Info Services Pvt Ltd, you will be responsible for designing and implementing waveforms for wireless communication systems, including FHSS and FHSS-OFDM waveforms. You will collaborate with the RF team to ensure the delivery of robust wireless solutions for India's defence sector. Key Responsibilities: - Design FHSS waveforms for the Basic version with specific parameters such as 500 hops/s and QPSK modulation for half-duplex operation at 2 Mbps. - Develop FHSS-OFDM waveforms for the Advanced version with 64 subcarriers to enable full-duplex transmission over a 5 MHz bandwidth. - Port waveforms from MATLAB simulations to TI DSPs (C55x for Basic, C6748 for Advanced) with optimization of 20-50 MFLOPS. - Implement the designed waveforms on TI DSPs, ensuring waveform synchronization (<1 s jitter) and anti-jamming performance (13 dB gain vs. 20 dB J/S). - Collaborate with RF Engineers to integrate waveforms with RF hardware such as HackRF and AD9361. Qualification Required: - B.Tech/M.Tech in ECE, Electrical Engineering, or related field from a reputed institute. - 7+ years of experience in physical layer design and baseband processing for wireless systems. - Proficiency in waveform development including FHSS, OFDM, QPSK using MATLAB and C. - Hands-on experience with TI DSPs (C55x, C6748) and expertise in TI Code Composer Studio. - Knowledge of RF systems operating within the 350-450 MHz range and familiarity with defence-grade anti-jamming techniques. - Understanding of WPC/DoT regulations is a plus. - Strong problem-solving skills and the ability to work effectively in a lean, fast-paced team environment.
