There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the Receiver using DSSS plot the BER_awgn and BER_ray

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a Receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge

pashload是應(yīng)用在linux下的網(wǎng)絡(luò)帶寬測試源程序精確度比較高 ///////////////////////////////////// Pathload is a tool for estimating the available bandwidth of an end-to-end path from a host S (sender) to a host R (Receiver). The available bandwidth is the maximum IP-layer throughput that a flow can get in the path from S to R, without reducing the rate of the rest of the traffic in the path.

The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and Receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one Receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS Receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this Receiver to the SV s. The differences between measured ranges and calculated ranges at the reference Receiver are applied as corrections to the ranges measured by other Receiver(s) close by.

Modify the Gray-coded modulation example (COMMDOC_GRAY) so that it uses a pair of square root raised cosine filters to perform pulse shaping and matched filtering at the transmitter and Receiver, respectively.
