Lectures:

1. Foundations, The Wireless Channel (1 hour)
   Physical and statistical modeling of multipath wireless channels. Key parameters: delay spread, coherence bandwidth, coherence time, Doppler spread. Example: The Ultra-wideband channel.
2. Foundations, Diversity (1.5 hours)
   Diversity techniques. Time diversity: interleaving, rotation codes. Space diversity: transmit and receive diversity, space-time codes. Frequency diversity: ISI equalization, Rake receiver in CDMA systems, frequency hopping in OFDM systems. Cooperative diversity. Impact of channel uncertainty on diversity combining. Examples: GSM, 802.11A.
3. Foundations, Capacity of Wireless Channels (1.5 hour)
   Capacity notions for fading channels: outage capacity, fast fading capacity. Key performance measures: diversity, degree of freedom and power gains. High versus low SNR regimes. Waterfilling over time and over frequency. Example: rate adaptation in CDMA 2000 1x EV-DO.
