Description: Title: MMSE Receiver for DS-SS in AWGN Channel
Author: Panson Tantikovit
Summary: An adaptive receiver for DS-SS systems
MATLAB Release: R12.1
Required Products: Communications Toolbox,Signal Processing Blockset
Description: This is 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.

Description: 直接序列扩频通信可以有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在接收端,原伪噪声序列和所收信号的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声；同时，将DS信号解扩,恢复原始信息数据。-direct sequence spread spectrum communication can be effective resistance from the channel narrowband interference. In a DSSS system. Spreading through the sequence of pseudo-noise (PN) to send the right message to data modulation to achieve. On the receiving end, the original pseudo-noise sequence and the received signal may be related Operational narrowband interference signal DS extended to the whole band, make tampering equivalent to a lesser extent than the flat spectrum of noise; Meanwhile, the DS signal disspreaded restore the original data.

Description:
The main aim of our project is to simulate CDMA modem using DS-SS (Direct sequence spread spectrum) in MATLAB. Spread spectrum is basically type of modulation that spreads data transmission across available frequency band, in excess of minimum bandwidth available. We will be generating code by multiplying with pseudo random code in order to generate spread spectrum, transmitting it over a common frequency band and de-spreading the signal using same pseudo random code at the receiver. Also our aim is to simulate the de-spreading of the received CDMA signal in the presence of AWGN .
