SDAL Brief Description

The Signal Design and Analysis Laboratory (SDAL) is located within the Department
of Electrical and Computer Engineering
of Queen's University at Kingston on the 6th
floor of Walter Light Hall (room WLH 612). SDAL is directed by Prof. Shahram Yousefi
where currently a number of MASc, PhD, and NSERC-USRA researchers conduct leading edge studies
on a variety of topics in telecommunications.

In particular, the laboratory is currently involved in a number of projects and areas
toward the current and future generation communication systems, particularly in the
physical (PHY) layer. These include the design and analysis of signals and systems for
wireless systems as well as wired networks such as the best-effort network the Internet.

Our group collaborates with a number of other faculty members in the department as well
as the following laboratories:

  • Multimedia Coding and Communications Laboratory (MC2L) [Directed by Prof. Chan]
  • Advanced Multidimensional Signal Processing Laboratory (MSPL) [Directed by Prof. Gazor]
  • Wireless Information Transmission Laboratory (WITL) [Directed by Prof. Kim]
  • Prof. Aria Nosratinia, UT Dallas, USA

These collaborations provide a rich and solid foundation for researchers within the lab.
Members of the lab present their results at top-notch conferences and symposia and publish them in most prestigious journals in
the international level and on a regular basis. Most students at SDAL hold external
scholarships and/or industry financial support (e.g., NSERC PGS).

Current projects undertaken at SDAL on space-time code design and analysis and information and coding theory include:

  1. Analysis of spatial multiplexing and V-BLAST systems with ML decoders
  2. Low-complexity ML and sub-ML decoders for MIMO systems
  3. Optimal signal sets for MIMO applications
  4. Precoder design for MIMO systems
  5. Coded modulation and codes over rings and groups
  6. Nonbinary LDPC code design and analysis
  7. Iterative decoders for binary and nonbinary codes
  8. Efficient ML and near-ML decoders for block codes
  9. Network coding with random linear codes
  10. Throughout- and decoding-time-optimized network codes
  11. Finite buffer analysis of random linear network codes
  12. Iterative decoders for MIMO systems
  13. Physical-layer network coding
  14. Rateless codes for advanced architectures
  15. Rateless network codes
  16. Polar coding

Notes for Applicants

Positions are always available in both M.Sc. and Ph.D. levels on the availability of funds. Admission is usually granted along with full financial assistance but preference is given to students with NSERC or OGS scholarships. Under special circumstances, we do also consider very competent self-funded applicants. If you have external funding (NSERC, OGS, industry, foreign, etc.), admission is possible if you meet the minimum requirements of the School of Graduate Studies, Dept. of Electrical and Computer Eng., as well as my research group, and your area and background are deemed suitable for my current research projects. To qualify you must further:

  • be of great character, extremely organized, punctual, motivated, and personable
  • have a degree from an internationally well-known institution
  • have a very high GPA and be in top 5% of your class
  • have a very strong mathematical background, in particular, in linear/abstract algebra, group theory, probability theory, and random processes
  • be familiar with the fundamentals of communication and information theory (concepts such as block codes, AWGN channel, Viterbi decoding, digital modulation techniques, entropy, mutual information, etc.)
  • have good programming skills (MATLAB and C/C++/Java)
  • have strong interest in producing publishable results in the area of digital communications (Publish or Perish!)
  • meet the English language requirement of the school of graduate studies easily (e.g. TOEFL) and be proficient in speaking, (technical) writing, and comprehension

If you think you meet the above requirements, please send your resume (in ps or pdf formats) to me. In your resume, please indicate your immigration status (Canadian, permanent resident, or international). Also indicate if you hold, have applied for, or plan to apply for any funding or scholarship (e.g., NSERC, OGS, etc.). Strong applicants with funding from governments, organizations, and companies, nationally and internationally, are invited to apply.

Important Notice: Due to the large number of applications and emails, I am not able to reply to each and every one of them. I will contact you only if I need further information.
