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

Example of a digital data transmission implementing GMSK modulation
This Simulink model simulates as an example the transmission and reception of random digital data modulated with GMSK. The purpose of this model is to illustrate how part of the GSM transmission and reception works. It also measures the BER, affected by an AWGN channel
The new digital radio system DAB (Digital Audio Broadcasting, nowadays often called
Digital Radio) is a very innovative and universal multimedia broadcast system which will
replace the existing AM and FM audio broadcast services in many parts of the world in
the future. It was developed in the 1990s by the Eureka 147/DAB project. DAB is very
well suited for mobile reception and provides very high robustness against multipath
reception. It allows use of single frequency networks (SFNs) for high frequency
efficiency.
Introduction to Radio Frequency Identification (RFID): RFID is a
wireless modulation and demodulation technique for automatic
identification of objects, tracking goods, smart logistics, and access con-
trol. RFID is a contactless, usually short‐distance transmission and
reception technique for unique ID data transfer from a tagged object to
an interrogator (reader). The generic configuration of an RFID system
comprises (i) an ID data‐carrying tag, (ii) a reader, (iii) a middleware,
and (iv) an enterprise application.
Identification is pervasive nowadays in daily life due to many complicated activities such as
bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data
and procedures and target identification. This kind of task can be realized by passwords, bio-
metric data such as fingerprints, barcode, optical character recognition, smart cards and radar.

It is a contactless, usually short distance, wireless data transmission and reception technique
for identification of objects. An RFID system consists of two components: the tag (also called
transponder) and the reader (also called interrogator).
