The PCA9546A is a quad bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to four downstream pairs, or CHANNELs. Any individualSCx/SDx CHANNEL or combination of CHANNELs can be selected, determined by thecontents of the programmable control register.
The PCA9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.The SCL/SDA upstream pair fans out to eight downstream pairs, or CHANNELs. Only oneSCx/SDx CHANNEL can be selected at a time, determined by the contents of theprogrammable control register. The device powers up with CHANNEL 0 connected, allowingimmediate communication between the master and downstream devices on that CHANNEL.
The PCA9548A is an octal bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to eight downstream pairs, or CHANNELs. Any individualSCx/SDx CHANNEL or combination of CHANNELs can be selected, determined by thecontents of the programmable control register.An active LOW reset input allows the PCA9548A to recover from a situation where one ofthe downstream I2C-buses is stuck in a LOW state. Pulling the RESET pin LOW resets theI2C-bus state machine and causes all the CHANNELs to be deselected as does the internalPower-on reset function.
This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN CHANNEL. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain
This packet is a IS-95 baseband simulation for 1 data CHANNEL of 9.6 KBps rate. The simulation is written for static CHANNEL and AWGN noise.
The packet include:
1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)
2) Modulator (RRC filter)
3) Demodulator (Matched Filter, RAKE receiver)
4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).
You should run "Simulation.m" function that include all modules.
The IEEE Multipath CHANNEL block simulates an indoor UWB CHANNEL as described in "A CHANNEL Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.
his folder contains the following files:
1. 02490rxP802-15_SG3a-CHANNEL-Modeling-Subcommittee-Report-Final.doc: This is the final
report of the CHANNEL modeling sub-committee.
2. cmx_imr.csv (x=1, 2, 3, and 4) represent the files containing the actual 100 CHANNEL
realizations for CM1, CM2, CM3, and CM4. The columns are organized as (time, amp, time, amp,...)
3. cmx_imr_np.csv (x=1, 2, 3, and 4) represent the files containing the number of paths in
each of the 100 multipath realizations.
4. cmx_imr.mat (x=1, 2, 3, and 4) are the .mat files that can be loaded directly into
Matlab (TM).
5. *.m files are the Matlab (TM) files used to generate the various CHANNEL realizations.
