IEEE 802.11 a b and g - BBP core for Wireless LAN

Overview

BBP is a PHY entity for an OFDM and DSSS, aimed for data transfer rates upto 54 Mbps at the unlicensed frequency range of 2.4 and 5 GHz. This specification describes the functions of the signal processing in the medium and the interface with the radio.
BBP Core is designed to be used at higher speeds providing maximum performance with minimum power consumption. High decode gain Viterbi algorithm for added performance. The Baseband processor can interface to an RF using either an analog I/Q interface or a digital interface.

Key Features

Fully Compliant to IEEE 802.11a IEEE 802.11b and IEEE 802.11g PHY layer functions and frames.
Interfaces with most existing RF. Compactable with TI RC2436B.
Data rates up to 11 Mbit/sec (802.11b) and 54 Mbit/sec (802.11a and 802.11g).
It is based on the Fast Fourier transform (FFT) concept, which allows the multiple subcarriers to overlap yet maintain their integrity.
High throughput data rates are achieved in OFDM due to precise carrier spacing and exact amplitude and phase settings for each individual carrier constellation.
Forward Error Correction coding to improve the data relaiability.
The sensitivity as well as multi-path tolerance of the BBP is among the best in the industry.
Optimized for Low Power Consumption
Optimum hardware-software partitioning for reduced gate count as well as lower MIPS requirements.
