Space-Time Convolutional Codes Over GF(p) for the Quasi-Static, Flat Rayleigh Fading Channel

Efficient Simulation of Space-Time Block Codes and Concatenated Convolutional Codes over Quasi-static Fading Channels

Space-Time Block Coding (STBC) is a very attractive space-time coding scheme that can offer a maximum possible diversity advantage with very simple maximum likelihood decoding at the receiver. To further improve the code performance, a concatenated coding scheme which consists of an outer convolutional code with an inner space-time block code has been proposed. Because of the system complexity,...

A Review of Space time trellis codes with ideal beamforming for quasi-static Rayleigh fading channel

I. Introduction Multiple-input and multiple-output (MIMO), uses multiple antennas at both the transmitter and receiver to improve communication performance. MIMO technology has involved consideration in wireless communications, as it offers major increase in data throughput and link range without further bandwidth or increased transmit power. It attains this goal by distributing the same total ...

The Design of Linear Space-Time Codes for Quasi-static Flat-fading Channels

Cutoff rate and signal design for the quasi-static Rayleigh-fading space-Time channel

We consider the computational cut-o rate and its implications on signal design for the complex quasistatic Rayleigh at fading spatio-temporal channel under a peak power constraint where neither transmitter nor receiver know the channel matrix. The cut-o rate has an integral representation which is an increasing function of the distance between pairs of complex signal matrices. When the analysis...

Improved space-time convolutional codes for quasi-static slow fading channels

Space-time convolutional codes, that provide maximum diversity and coding gain, are produced for cases with PSK modulation and various numbers of states and antennas. The codes are found using a new approach introduced recently in a companion paper. The new approach provides an eecient method that allows a search for optimum codes for many practical problems. The new approach also provides a si...
