"
"\n* End-to-end physical layer (streaming mode)
\n* Highest mandatory data rat"

\n* QPSK modulation, rate-5/8 forward error correction coding (c"
"onvolutional + puncturing)
\n* OFDM transmission: 122 subcarriers, 22 pilots,"
" 128-pt FFTs, zero prefix, guard period
\n* Fixed-point model of OFDM TX/RX ("
"16-, 12-, 10-, and 8-bit)

\n* PLCP preamble (packet sync, frame sync, and channel estimation)

\nMODEL ASSUMPTION"
"S
\n* Baseband-equivalent model (no up/down RF conversion)
\n* Random data tr"
"ansmision (no data scrambling used)
\n* Fixed (selectable) number of data sym"
"bols per packet (no pad bits used)
\n* Continuous frame-to-frame operation (n"

\n* Fixed transmit power level; link-S"

\n* Idealized timing/frequency acquisition
\n* Not "

\n - Other mandatory and optional data rates (55, 80, 110, 160, "
"200, 320, 480 Mb/s)
\n - MAC/PHY interface and PLCP header (TXVECTOR/RXVEC"

\n - Time windowing of OFDM symbols

\nCHANNEL MODELS
\nTh"
"is model requires four .mat files to run. These can be obtained from:
\n ht"
"tp://grouper.ieee.org/groups/802/15/pub/2003/Mar03/
\nThe files are contained"
" in
\n 02490r1P802-15_SG3a-Channel-Modeling-Subcommittee-Report-Final.zip
"
"\nThis is a rather large file, about 16M in size. It also includes M-files t"
"hat
\ncan be used to create the four .mat files. On loading, the UWB model "
"automatically
\nexecutes these M-files if the .mat files do not exist.

\nOTHER MODEL NOTES
\n* Model is configured for presentations:
\n - Simu"
"lation stop time is set to inf
\n* Channel impulse response only plots when s"
"imulation is stoppped
\n* Blocks involving fixed-point arithmetic are highlig"

\nIf you use fixed-point settings to override the data types f"
"or any of these blocks,

" update the model.
