1 Stagnation in Physical Layer Research an Industry Perspective NAE-NATF Event, , Chantilly, France Wireless Broadband Session Stephan ten Brink University of Stuttgart Institute of Telecommunications Pfaffenwaldring Stuttgart, Germany
2 One reason why I am here today 2
3 WHAT is the Physical Layer? Application (webbrowser) internet transport (TCP) Operating system "gateway" medium access (MAC) network (IP) driver Access point (WLAN/UWB Base station) WLAN/UWB network card bit transmission (PHY) medium access (MAC) bit transmission (PHY) channel 3
4 The Physical Layer: How it works 4
5 Physical Layer: The Spectral Resources MHz GHz bandwidth THz Wired cable: available ca. 1GHz bandwidh, i.e., can carry Mb/s..Gb/s Wireless - Wireless access, ca. 1GHz bandwidth, Mb/s..Gb/s - Point-to-point: several GHz bandwidth Optical: 200THz bandwidth 5
6 Wireless Network Structure macro basestation 1. Wireless Access (Mb/s) metro 2. Backhaul (Gb/s) 3. Optical core network (Tb/s) Physical layers involved in wireless broadband Cellular concept: spatially reuse spectrum
7 Outline Wireless Perspective Optical Perspective Summary 7
8 The Theoretical Frontier How to get there? 8
9 From HARD Decision XXX XXX x - x x» x xxx 9
10 to SOFT Detection. XXX XXX x - x x» x xxx 10
11 From ONE-SHOT to ITERATIVE/JOINT processing source sink X2 E2 outer encoder Y2 IA2-1 IE1 inner encoder modulator A2 SOFT, ITERATIVE X1 Y1 outer decoder AWGN N A1 a priori knowledge inner decoder LD demodulator X E1 extrinsic (new) knowledge Y I(X;Y) 11
12 Soft, iterative Processing: We did it! 12
13 The next frontier Advances in theory and implementation - Posed hardware challenge over the past decade - But today: solved - Single link (point-to-point) Shannon limit pretty much achieved What was NEXT? - Multi-antenna processing - Investment in detection algorithms - up to 8 antennas in widespread use (since about 2005) 13
14 Pushing the frontier through multiple antennas 14
15 The new frontier: Scaling it up and precoding What about using hundreds of antennas? - to further increase data rate per cubic meter - interference mitigation through precoding First prototypes built, channel measurements done Challenges - Channel modelling - Exploit channel reciprocity to avoid training - Transmit/receiver calibration - wiring, connectivity how to integrade with facade T. L. Marzetta, IEEE Trans. Wireless Commun., vol. 9, no. 11, Nov J. Hoydis et al., JSAC, vol. 31, n. 2, Feb
16 Large antenna arrays Scalable prototype at Bell Labs (Oct. 2013), design target 1024 antennas 16
17 Conventional Deployment Few base station antennas Concept of cells, sectors, for frequency reuse, interference mitigation 17
18 Delpoyment scenario with large antenna arrays Distributed, massive number of antennas Interference mitigation through matrix precoding at basestation Increase data rate per cubic meter by factor
19 Requires new basestation architecture (1/3) Initial base station deployment (GSM, 1990s): - long RF cables - Several dbs in power loss 19
20 Requires new basestation architecture (2/3) Introduction of Remote Radio Heads, 2000s - short RF cables - Digital interface 20
21 Requires new basestation architecture (3/3) Silicon Antenna : add highly integrated chip to antenna - Very short RF cables; amplifiers right at antenna - Novel distributed algorithms Investment in Mixed-Signal ASICs: high volume, low-cost 21
22 Outline System Overview and Wireless Perspective Optical Perspective Summary 22
23 Spectral Overview MHz GHz bandwidth THz Wireless, GHz Optical: 200THz, vast bandwidth resources - backhaul/core network must not become the bottleneck What are the limits? 23
24 Innovations over the past decade 24

26 XXX 100GBaud-Signal after 50km XXX x - x x» x 26
27 State of the Art Prior to coherent detection in optics - Dispersion compensation in analog (special compensating fiber) With advent of coherent detection (around 2005 ) - Digital compensation - Other linear/non-linear impairments can be mitigated Heavy investment in silicon chips (ASICs)! Also, special error detecting/correcting codes needed - Very low bit error rates in optical: 1e-15 (wireless access: 1e-4) - New kid on the block: Spatially coupled codes Optics a communication engineer s dream Physical layer can be proprietary, no standardization needed! 27
28 Peak Power Limited; Next Frontier: Space? R.-J. Essiambre et al., J. Lightwave Technol. 28, 662 (2010). 28
29 From 2 to 100s of Spatial Modes Single-mode fibers One spatial mode but support two modes (two polarization states) Used for distances > 1km Multimode fibers Can support a few or many spatial modes For short reach (~ 100 meters) Few-mode fiber Multimode fiber Multicore fibers Can exhibit coupling or not between cores Coupled-core fibers support supermodes 3-core 7-core 19 -core [C.R.Doerr et al.]
30 Summary and Outlook Wireless access - Point-to-point links: theoretical limits achieved - Cellular infrastructure goes massive, and consumer electronics Optical backhaul/core - Coherent detection state of the art, 400Gb/s per 100GHz bandwidth - Room for further improvements: signal processing (ASICs) and coding - Next frontier: Multicore fibers and associated algorithms, technology 30
